ASoC: codecs: wcd934x: add explicit soundwire depenency

WCD934x provides register read/write interface to soundwire controller via
slimbus. Eventhough there was no direct compile time dependency for
this so far, however after adding common wcd functions this dependency
became explict.

We can either move the soundwire specific bits from wcd-common to wcd-sdw.c or
something on those lines or explicity add this dependency in Kconfig.
Moving this wcd-sdw can fix reported compile issue but it does not make
sense to select this codec without soundwire configs.
Given the fact that WCD934x is very much providing soundwire functionality
it is better to specify the soundwire dependency explicity in Kconfig
which should also fix the below compile time error with combination
of wcd934x a built-in and soundwire a module and also allow this codec
selection only when soundwire is available.

Error log:
wcd-common.c:undefiined reference to `sdw_write'
sound/soc/codecs/wcd-common.o: in function `wcd_bus_config':
