Drop the own refcount but use the standard device refcounting via
get_device() and put_device(). Introduce a new completion to snd_card
instead of the wait queue for syncing the last release, which is used
in snd_card_free().

As prepared in the previous patch, we are ready to create a device
struct for the card object in snd_card_create() now. This patch
changes the scheme from the old style to:
- embed a device struct for the card object into snd_card struct,
- initialize the card device in snd_card_create() (but not register),
- registration is done in snd_card_register() via device_add()
The actual card device is stored in card->card_dev. The card->dev
pointer is kept unchanged and pointing to the parent device as before
for compatibility reason.

Commit f7d3c1709 ("ASoC: dapm: Change prototype of soc_widget_read") changed the
signature of soc_widget_read() so that it, instead of return the register value
as a int, takes a pointer to a unsigned int and stores the register value in
that pointer. There are still a few places that pass a int type value to that
function though. Change these to unsigned int. For more consistency also change
the signature of soc_widget_write() to take a unsigned int instead of an int for
the register value.

Sync regcache when entering STANDBY from OFF. ON isn't entered with
OFF as the current state, so the registers were not being re-synced
after suspend/resume.
The 98088 and 98095 already call regcache_sync from STANDBY.

Since the machine driver selects the CODEC driver we need to make sure that the
machine driver is only selectable if the CODEC driver can be build. This avoids
build errors under some configurations (which typically only result from
randconfig).

This is a part of preliminary works for modernizing the ALSA device
structure. So far, we set card->dev at later point after the object
creation. Because of this, the core layer doesn't always know which
device is being handled before it's actually registered, and it makes
impossible to show the device in error messages, for example. The
first goal is to achieve a proper struct device initialization at the
very beginning of probing.
As a first step, this patch introduces snd_card_new() function (yes
there was the same named function in the very past), in order to
receive the parent device pointer from the very beginning.
snd_card_create() is marked as deprecated.
At this point, there is no functional change other than that. The
actual change of the device creation scheme will follow later.

As part of phasing out the ASoC level register I/O code (which is now just
a thin wrapper around regmap anyway) convert the cs42l51 driver to use the
regmap API directly.
We now no longer initialise the cache from hardware at startup, the regmap
caches are smart enough to understand which registers are actually cached
and read on demand. This should have no visible effect on the system.

Currently the I2C device Ids conflict for the MFD and CODEC so
cannot be both instantiated on one platform. This patch updates
the Ids and names to make them unique from each other.
It should be noted that the I2C addresses for both PMIC and CODEC
are modifiable so instantiation of the two are kept as separate
devices, rather than instantiating the CODEC from the MFD code.
