[PATCH 2/2] Compiler Attributes: auxdisplay: panel: use __fallthrough

[Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>]

Let gcc know these cases are meant to fall through to the next label
by annotating them with the new __fallthrough statement attribute;
and remove the comment since it conveys the same information
(which was also parsed by gcc to suppress the warning).
