CS35L41 supports hibernation during suspend when using
DSP firmware.
When the driver suspends it will hibernate the part, if
firmware is running, and resume will wake from hibernation.
CS35L41 driver will suspend/resume when requested by
hda driver.
Note that suspend/resume and hibernation is only supported
when firmware is running.

ACPI_PTR() is more harmful than helpful. For example, in this case
if CONFIG_ACPI=n, the ID table left unused which is not what we want.
Instead of adding ifdeffery or attribute here and there, drop ACPI_PTR().

The comments are inconsistent and point to the wrong driver name.
The initially named i2c-multi-instantiate it was renamed to the
serial-multi-instantiate exactly due to support of the platforms
with multiple CS35L41 codecs.
Fix comments accordingly.
While at it, drop file names from the files.

Up to now cs35l41_hda_remove() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.
Also the return value of i2c and spi remove callbacks is ignored anyway.
