ASoC: codecs: wcd938x: remove incorrect module interdependency 

For some reason we ended up with cyclic dependency between snd_soc_wcd938x
and snd_soc_wcd938x_sdw modules.

Remove this cyclic dependency by handling them in respective modules.
Without this below error is reported during make modules_install

depmod: ERROR: Cycle detected: snd_soc_wcd938x -> snd_soc_wcd938x_sdw -> snd_soc_wcd938x
depmod: ERROR: Found 2 modules in dependency cycles!
