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.
