Subject: [PATCH v2 1/2] soundwire: fix SOUNDWIRE_BUS option

The existing Kconfig can lead to the following warning:

WARNING: unmet direct dependencies detected for REGMAP_SOUNDWIRE
  Depends on [m]: SOUNDWIRE_BUS [=m]
  Selected by [y]:
  - SND_SOC_RT700_SDW [=y] && SOUND [=y] && !UML && SND [=y] &&
    SND_SOC [=y] && SOUNDWIRE [=y]
  Selected by [m]:
  - SOUNDWIRE_BUS [=m] && SOUNDWIRE [=y]

Remove wrong-way link between SOUNDWIRE_BUS and REGMAP_SOUNDWIRE

SOUNDWIRE_BUS can be selected independendly by the SOC driver
(e.g. SOUNDWIRE_INTEL) or the codec driver (via REGMAP_SOUNDWIRE).

Fixes: 6c49b32d3c09 ('soundwire: select REGMAP_SOUNDWIRE')
