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

["Gustavo A. R. Silva" <garsilva@embeddedor.com>]

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.
