Subject: [PATCH] ASoC: Intel: boards: Fix CONFIG_SND_SOC_SDW_MOCKUP select

When CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH is enabled without
CONFIG_EXPERT, there is a Kconfig warning about unmet dependencies:

WARNING: unmet direct dependencies detected for SND_SOC_SDW_MOCKUP
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] &&
EXPERT [=n] && SOUNDWIRE [=y]
  Selected by [y]:
  - SND_SOC_INTEL_SOUNDWIRE_SOF_MACH [=y] && ...

Selecting a symbol does not account for dependencies so if symbol A
selects symbol B which depends on symbol C, symbol B or its select of
symbol A should depend on symbol C as well.

Make the CONFIG_SND_SOC_SDW_MOCKUP select in
CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH depend on CONFIG_EXPERT as the
help text for CONFIG_SND_SOC_SDW_MOCKUP indicates it is intended to be a
development option.

An alternative here is if CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH wants
to unconditionally select CONFIG_SND_SOC_SDW_MOCKUP, the "depends on
EXPERT" can be moved to the prompt (tristate "..." if EXPERT). I am
happy to send a new patch if that is what is desired.
