[PATCH v7 00/16] Support external boost at CS35l41 ASoC driver

[Lucas Tanure]

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.

v7 changelog:
 - Rebased on top v5.18-rc2 tag
 - Acks from Mark Brown

v6 changelog:
 - Rebased on top of Linux Next with community patches for CS35L41
 - Document patch acked by Charles Keepax

v5 changelog:
 - Fixed wrong indentation at Documentation patch
 - Use of consistent prefix

v4 changelog:
 - Separated GPIO 1 and 2 function enums

v3 changelog:
 - Remove patches already accepted
 - Improved logic in documentation patch
 - Documentation patch goes before its code
 - Fixed missing Signed-off-by
 - Fixed subject for HDA patches

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.
