[PATCH][next] drm/amd/pm: Fix fall-through warning for Clang

[Gustavo A. R. Silva]

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a break 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 22 in linux-next. This is one of those last remaining
      warnings. :)
