Improve FRV's use of generic IRQ handling:
(*) Use generic_handle_irq() rather than __do_IRQ() as the latter is obsolete.
(*) Don't implement enable() and disable() ops as these will fall back to
using unmask() and mask().
(*) Provide mask_ack() functions to avoid a call each to mask() and ack().
(*) Make the cascade handlers always return IRQ_HANDLED.
(*) Implement the mask() and unmask() functions in the same order as they're
listed in the ops table.

Make the FRV arch use the generic IRQ code rather than having its own
routines for doing so.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
