sh: Drop CPU subtype IRQ headers.

This drops the various IRQ headers that were floating around and primarily providing hardcoded IRQ definitions for the various CPU subtypes. This quickly got to be an unmaintainable mess, made even more evident by the subtle breakage introduced by the SH-2 and SH-2A changes. Now that subtypes are able to register IRQ maps directly, just rip all of the headers out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
