sh: Rework CPU/board dependencies.
This was a big mess, rework the logic a bit so that we constrain to a particular subtype and figure out the board support based on that. This makes building subtype specific kernels supporting multiple boards possible again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
