Subject: [PATCH 002/141] ASoC: codecs: Fix fall-through warnings for Clang

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding multiple break statements instead of just
letting the code fall through, and also add fallthrough pseudo-keywords
in places where the code is intended to fall through to the next case.
