This patch suggests enabling pm_runtime during the probe, but marking the
device as 'active' only after it is enumerated. That will force a
dependency between the card and the codec, pm_runtime_get_sync() will
have to wait for the codec device to resume and hence implicitly wait
for the enumeration/initialization to be completed. In the nominal
case where the codec device is already active the get_sync() would
only perform a ref-count increase.
The changes are directly inspired by RT711 and RT711-sdca changes.

The SoundWire bus may start after the probe where the SoundWire ASoC
components are registered. This creates a time window where the card
can be created and the registers be accessed.
As discussed on the mailing list, we can't really control when codecs
are enumerated and initialized, but we can make sure the access to the
codecs is cached until the hardware is accessible.
This patch configures regcache_cache_only() with a 'true' parameter in
the probe function, and a 'false' parameter in the io_init routine.
The rt5682 is handled through a different patch due to its specific
cache handling.

The max98363 driver provides cache defaults for a number of volatile
registers. This is not meaningful, the cache values will never be used so
at best they will just consume memory and at worst they will be used in
preference to real values from the device, remove them.

MAX98363 does not support 32bit depth audio.
Removed 32bit from the supported format list.
Instead, added 16bit and 24bit to the list.
