Static arrays/structs for regmap configuration like 'struct
reg_default', 'struct reg_sequence' and others are not modified so can
be changed to const for more safety.

Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros
instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together
with pm_ptr(), which allows us dropping superfluous CONFIG_PM and
CONFIG_PM_SLEEP ifdefs.
This optimizes slightly when CONFIG_PM is disabled, too.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Instead of relying on legacy interfaces, convert the driver to
use GPIO descriptors. This is a straight-forward conversion,
we support also sdw devices providing GPIO descriptor tables
if they so desire.

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.

This register value was not able to be synced because it was marked as

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.
