ASoC: codecs: wcd93xx: fix object added to multiple drivers

Three Qualcomm audio codecs (WCD9355, WCD934x and WCD938x) use the same
object file wcd-clsh-v2.o leading to warnings:

  Makefile: wcd-clsh-v2.o is added to multiple modules: snd-soc-wcd9335 snd-soc-wcd934x snd-soc-wcd938x

Convert the wcd-clsh-v2.o to a module to solve it.
