Subject: [PATCH] watchdog: ib700wdt: mark expected switch fall-through

Precedence: bulk

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

Notice that in this particular case I replaced "Fall" with a proper
"fall through" comment, which is what GCC is expecting to find.
