[PATCH] auxdisplay: panel: mark expected switch fall-throughs

[PATCH] auxdisplay: panel: mark expected switch fall-throughs

[Gustavo A. R. Silva]

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

In this particular case, notice that I replaced the "no break here,
fall through" comments with "fall through" comments, which is what
GCC is expecting to find.

Thanks! I will put it in my queue (I sent a similar one a few days
ago, so I will pick yours).
