Okay, so the patch description says "This needs to be 12 on this platform".

but you leave it up to the user to select something that may not be
suitable.  Wouldn't _just_ adding:

	default "12" if SOC_AM33XX

after the "range", and making no other changes be good enough and match
what the patch description says?
