The existing code has a mixed select/depend usage which makes no sense.

config SOUNDWIRE_BUS
        tristate
        select REGMAP_SOUNDWIRE

config REGMAP_SOUNDWIRE
         tristate
         depends on SOUNDWIRE_BUS

Let's remove one layer of Kconfig definitions and align with the
solutions used by all other serial links.

Vinod, Mark, any feedback?

There will be a set of SoundWire codec drivers provided upstream soonish and we'll get a number of kbuild errors without this patch.
