Subject: [PATCH v2 00/20] Support external boost at CS35l41 ASoC driver

Move the support for CS35L41 external boost to its shared library
for ASoC use.
This move resulted in cs35l41_hda_reg_sequence being removed,
and its steps were broken down into regmap writes or functions
from the library. And hardware configuration struct was unified
for its use in the shared lib.
While at it, some minor bugs were found and fixed it.

v2 changelog:
 - Instead of removing the log, playback actions will log the last regmap access.
 - Documentation patch with the correct subject line and fixed bug reported by Rob Herring on the
 provided example.
