mmc: tifm_sd: Mark expected switch fall-through 

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
"deliberate fall-through" comment with a proper "fall through"
at the bottom of the case, which is what GCC is expecting to find.
