Subject: [PATCH][next] ASoC: ti: davinci-mcasp: Fix fall-through warning for
 Clang

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a goto statement instead of letting the code fall
through to the next case.

JFYI: We had thousands of these sorts of warnings and now we are down
      to just 25 in linux-next. This is one of those last remaining
      warnings.
