ASoC: qcom: lpass-cpu: Make I2S SD lines configurable
The LPASS hardware allows configuring the MI2S SD lines to use
when playing/recording audio. However, at the moment the lpass-cpu
driver has SD0 hard-coded for mono/stereo (or additional fixed
SD lines for more channels).

For weird reasons there seems to be hardware that uses one of the
other SD lines for mono/stereo. For example, some Samsung devices
use an external Speaker amplifier connected to Quaternary MI2S.
For some reason, the SD line for audio playback was connected to
SD1 rather than SD0. (I have no idea why...)
At the moment, the lpass-cpu driver cannot be configured to work
for the Speaker on these devices.

The q6afe driver already allows configuring the MI2S SD lines
through the "qcom,sd-lines" device tree property, but this works
only when routing audio through the ADSP.

This commit adds a very similar configuration for the lpass-cpu driver.
It is now possible to add additional subnodes to the lpass device in
the device tree, to configure the SD lines for playback and/or capture.
E.g. for the Samsung devices mentioned above:

&lpass {
	dai@3 {
		reg = <MI2S_QUATERNARY>;
		qcom,playback-sd-lines = <1>;
	};
};

qcom,playback/capture-sd-lines takes a list of SD lines (0-3)
in the same format as the q6afe driver. (The difference here is that
q6afe has separate DAIs for playback/capture, while lpass-cpu has one
for both...)

For backwards compatibility with older device trees, the lpass-cpu driver
defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing.
This is equivalent to the previous behavior: Up to 8 channels can be
configured, and SD0/QUAT01 will be chosen when setting up a stream
with fewer channels.

This allows the speaker to work on Samsung MSM8916 devices
that use an external speaker amplifier.

97c52eb969 ASoC: qcom: move clock names into LPASS variant struct
The clock names for the two supported codecs are either
"mi2s-*" name variants generated by code. This naming scheme
does not work for platforms like MSM8660 which has I2S channels
named CODEC_I2S_SPKR (rather than just "MI2S tertiary" and other
repetitive names) and consequently have clocks named
"codec-i2s-spkr-osr-clk" and similar.

Skip the runtime generation of clock names and replace it with
name lookup tables encoded into the variant data.

8faa268ab7 ASoC: qcom: Don't specify LE device endianness
This reverts commit 18560a4e3 (ASoC: qcom: Specify LE device
endianness).

The commit that caused us to specify LE device endianness here,
29bb45f25f (regmap-mmio: Use native endianness for read/write,
2015-10-29), has been reverted in mainline so now when we specify
LE it actively breaks big endian kernels because the byte
swapping in regmap-mmio is incorrect. Let's revert this change
because it will 1) fix the big endian kernels and 2) be redundant
to specify LE because that will become the default soon.

18560a4e3b ASoC: qcom: Specify LE device endianness
This is a little endian device, but so far we've been relying on
the regmap mmio bus handling this for us without explicitly
stating that fact. After commit 4a98da2164cf (regmap-mmio: Use
native endianness for read/write, 2015-10-29), the regmap mmio
bus will read/write with the __raw_*() IO accessors, instead of
using the readl/writel() APIs that do proper byte swapping for
little endian devices.

So if we're running on a big endian processor and haven't
specified the endianness explicitly in the regmap config or in
DT, we're going to switch from doing little endian byte swapping
to big endian accesses without byte swapping, leading to some
confusing results. Specify the endianness explicitly so that the
regmap core properly byte swaps the accesses for us.
