net: dp83640: Mark expected switch fall-throughs

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

Notice that in this particular case, I replaced the code comment at the
top of the switch statement with a proper "fall through" annotation for
each case, which is what GCC is expecting to find.
