Subject: [PATCH v2 0/2] soundwire: fix Kconfig select/depend issues

0-day/Kbuild starts complaining about missed module dependencies and
compilation issues. Since codecs and soc drivers need to be compilable
independently, let's fix this using the following model:

SOF_INTEL_XYZ --- select ---->  SOUNDWIRE_INTEL ---> select ----
                                                               |
				                               v
                                                        SOUNDWIRE_BUS
   							       ^
                                                               |
CODEC_ABC ------- select -----> REGMAP_SOUNDWIRE ---> select ---

The SOUNDWIRE option remains a top-level boolean selector without
impact on compilation, as recommended by Linus [1] and done for all
Intel ASoC stuff.

Changes since v1:
Removed useless depend in REGMAP_SOUNDWIRE (select will ignore dependencies)
Reordered patches to avoid circular dependencies with git bisect

Pierre-Louis Bossart (2):
  soundwire: fix SOUNDWIRE_BUS option
  regmap: soundwire: fix Kconfig select/depend issue
