Do not include pm_runtime.h header in files where runtime PM support is
not implemented. Use pm.h instead as suspend to RAM specific
implementation is available.

After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

As the devm_kcalloc may return NULL pointer,
it should be better to check the return value
in order to avoid NULL poineter dereference.

The 0x203E speaker gain register should be non-volatile.
This register value was not able to be synced because it was marked as
volatile.

The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.
This avoids scanning the identifier tables during probes.

0x20FF(amp global enable) register was defined as non-volatile,
but it is not. Overheating, overcurrent can cause amp shutdown
in hardware.
'regmap_write' compare register readback value before writing
to avoid same value writing. 'regmap_read' just read cache
not actual hardware value for the non-volatile register.
When amp is internally shutdown by some reason, next 'AMP ON'
command can be ignored because regmap think amp is already ON.

We will set regcache_cache_only true in suspend. As a result,
regmap_read will return error when we try to read volatile
registers in suspend. Besides, it doesn't make sense to read
feedback data when codec is not active. To make userspace
happy, this patch returns a cached value shich should be a
valid value.

To prepare support for SoundWire, let's first split the I2C and common
parts. No new functionality, just indents and formatting to make
checkpatch happy.
