[PULL 3/8] hw/timer/sh_timer: Silence warnings about missing fallthrough statements

[Philippe Mathieu-Daudé]

From: Thomas Huth <thuth@redhat.com>

When compiling with -Werror=implicit-fallthrough, gcc complains about
missing fallthrough annotations in this file. Looking at the code,
the fallthrough is very likely intended here, so add some comments
to silence the compiler warnings.

Fixes: cd1a3f6840e ("Stand-alone TMU emulation code")
