Make sure to balance the runtime PM operations, including the disable
count, on probe errors and on driver unbind.

Make sure to deregister the component when the driver is being unbound
and before the underlying device-managed resources are freed.

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the wcd938x driver to use the more modern data structure.

regmap-sdw does not support multi register writes, so there is
no point in setting this flag. This also leads to incorrect
programming of WSA codecs with regmap_multi_reg_write() call.
This invalid configuration should have been rejected by regmap-sdw.

The WCD938x comes with three devices on two Linux drivers:
1. RX Soundwire device (wcd938x-sdw.c driver),
2. TX Soundwire device, which is used to access devices via regmap (also
wcd938x-sdw.c driver),
3. platform device (wcd938x.c driver) - glue and component master,
actually having most of the code using TX Soundwire device regmap.
When RX and TX Soundwire devices probe, the component master (platform
device) bind tries to write micbias configuration via TX Soundwire
regmap. This might happen before TX Soundwire enumerates, so the regmap
access fails. On Qualcomm SM8550 board with WCD9385:
qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops)
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops)
qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow
Fix the issue by:
1. Moving the regmap creation from platform device to TX Soundwire
device. The regmap settings are moved as-is with one difference:
making the wcd938x_regmap_config const.
2. Using regmap in cache only mode till the actual TX Soundwire device
enumerates and then sync the regmap cache.

For some reason we ended up with cyclic dependency between snd_soc_wcd938x
and snd_soc_wcd938x_sdw modules.
Remove this cyclic dependency by handling them in respective modules.
Without this below error is reported during make modules_install
depmod: ERROR: Cycle detected: snd_soc_wcd938x -> snd_soc_wcd938x_sdw -> snd_soc_wcd938x
depmod: ERROR: Found 2 modules in dependency cycles!
