ASoC: codecs: wcd938x: fix wcd module dependency
With SND_SOC_ALL_CODECS=y and SND_SOC_WCD938X_SDW=m, there is a link
error from a reverse dependency, since the built-in codec driver calls
into the modular soundwire back-end:
x86_64-linux-ld: sound/soc/codecs/wcd938x.o: in function `wcd938x_codec_free':
wcd938x.c:(.text+0x2c0): undefined reference to `wcd938x_sdw_free'
x86_64-linux-ld: sound/soc/codecs/wcd938x.o: in function `wcd938x_codec_hw_params':

x86_64-linux-ld: wcd938x.c:(.text+0x262a): undefined reference to `__devm_regmap_init_sdw'
Work around this using two small hacks: An added Kconfig dependency
prevents the main driver from being built-in when soundwire support
itself is a loadable module to allow calling devm_regmap_init_sdw(),
and a Makefile trick links the wcd938x-sdw backend as built-in
if needed to solve the dependency between the two modules.
