Add a flag to wm_adsp_power_up() that indicates whether it should attempt
to find and load firmware files.
This is to support DSPs that have built-in firmware that may already have
been patched (for example, by the BIOS). In that case the patch must not
be overwritten because that could corrupt the running firmware.

Existing HDA stream creation is split into two
for loops for capture and playback, but most of
the code in the two for loops are duplicated.
This patch refactors HDA stream creation with a
single for loop, thus remove code duplication.
No functional change in this patch.

The existing soc-dapm code may add a prefix to control names, which in
some cases is useful but in others leads to long and confusing kcontrol
names such as "gain 2.1 Main Playback Volume".
This patch suggests an added flag to prevent the widget name prefix
from being added. That flag will be set in the topology file on a
per-widget basis.
The flag no_wname_in_kcontrol_name is added to struct snd_soc_dapm_widget,
and the logic in dapm_create_or_share_kcontrol() is changed to not to
add widget name if the flag is set.

When the tdm lane mask is computed, the driver currently fills the 1st lane
before moving on to the next. If the stream has less channels than the
lanes can accommodate, slots will be disabled on the last lanes.
Unfortunately, the HW distribute channels in a different way. It distribute
channels in pair on each lanes before moving on the next slots.
This difference leads to problems if a device has an interface with more
than 1 lane and with more than 2 slots per lane.
For example: a playback interface with 2 lanes and 4 slots each (total 8
slots - zero based numbering)
- Playing a 8ch stream:
- All slots activated by the driver
- channel #2 will be played on lane #1 - slot #0 following HW placement
- Playing a 4ch stream:
- Lane #1 disabled by the driver
- channel #2 will be played on lane #0 - slot #2
This behaviour is obviously not desirable.
Change the way slots are activated on the TDM lanes to follow what the HW
does and make sure each channel always get mapped to the same slot/lane.

The ACPI setting for a GPIO default state has higher priority than the
flag passed to devm_gpiod_get_optional() so ACPI can override the
GPIOD_OUT_LOW. Explicitly set the GPIO low when hard resetting.
Although GPIOD_OUT_LOW can't be relied on this doesn't seem like a
reason to stop passing it to devm_gpiod_get_optional(). So we still pass
it to state our intent, but can deal with it having no effect.

Re-implement setting of ASP TDM slots so that only the common loop to
build the register word is factored out.
The original cs35l56_set_asp_slot_positions() had an apparent
uninitialized variable if the passed register address was neither of the
ASP slot registers. In fact this would never happen because the calling
code passed valid registers.
While it's trivial to initialize the variable or add a default case,
actually the only common code was the loop at the end of the function,
which simply manipulates some mask values and is identical for either
register. Factoring out the regmap_write() didn't really gain anything.
So instead re-implement the code to replace the original function with
cs35l56_make_tdm_config_word() that only does the loop, and change the
calling code to call regmap_write() directly.

The current code checks the first device on a link and assumes
that all the other devices on the link will have the same endpoint
aggregation status and endpoint group ID.
Say for example a system looked like:
SDW0 - Amp 1 (Aggregated, Group 1), Mic 1 (Aggregated, Group 2)
SDW1 - Amp 2 (Aggregated, Group 1), Mic 2 (Aggregated, Group 2)
The current code would create the DAI link for the aggregated amps,
although it is worth noting that the only reason Mic 2 is not added is
the additional check that aborts processing the link when the device
changes. Then when processing the DAI link for the microphones, Mic
2 would not be added, as the check will only be done on the first
device, which would be Amp 2 and thus the wrong group, causing the
whole link to be skipped.
Move the endpoint check to be for each device rather than the first
device on each link.

The current loops at the top of create_sdw_dailink process the devices
on each link starting from device index adr_index. But adr_index is only
meaningful on the first on these SoundWire links, as it is the index of
the current device on that link. This means devices will be skipped on
later links.
Say for example the system looks like this:
SDW0 - Codec (Not Aggregated), Amp 1 (Aggregated, Group 1)
SDW1 - Amp 2 (Aggregated, Group 1), Amp 3 (Aggregated, Group 1)
The code should create 2 DAI links, one for the CODEC and one for the
aggregated amps. It will create the DAI link for the codec no problem.
When it creates the DAI link for Group 1 however, create_sdw_dailink
will be called with an adr_index of 1, since that is the index of Amp
1 on SDW0. However, as the loop in create_sdw_dailink moves onto SDW1
it will again start from adr_index, skipping Amp 2. Resulting in the amp
DAI link only have amps 1 and 3 in it.
It is reasonable to start at adr_index on the first link, since
earlier devices have by definition already been processed. However,
update the code when processing later links to handle all devices.

There are two problems with the current range check on the codec_conf
array.
Firstly, adr_link_next->num_adr refers to the number of devices
on the current SoundWire link, but adr_index refers to the first
SoundWire link involved in the DAI link. This means that subtracting
these two numbers is only meaningful on the first SoundWire link in the
DAI and broken on later links.
Secondly, the intention of the range check is to add the number
of remaining devices on the currently link to the current index
and ensure enough space remains. However, this assumes that all
remaining devices on the SoundWire link will be added to the current
DAI link. Ideally this would not be the case, and devices could be
grouped as the user desired.
Moving the range check into the inner loop both simplifies the code (no
need to add and subtract offsets) and allows future refactoring such
that devices on a single SoundWire link don't have to all be grouped onto
a single DAI link. The check will be processed slightly more often since
it is processed for each device rather each link but this is probe time
and the numbers involved are very small here (4 links, likely no more
than 2-4 devices per link).
