[ Upstream commit 8676b3ca4673517650fd509d7fa586aff87b3c28 ]

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.
