[PATCH] sh: IRQ handler updates

This moves the various IRQ controller drivers into a new subdirectory, and
also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780
interrupts, rather than just ST-40.

The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as
new ports are expected to be based off of CONFIG_SH_UNKNOWN.  Since there are
plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.
