Daniel Stone 4c88ef170f omapfb: dispc: allow multiple external IRQ handlers
Previously, the only external (to dispc.c) IRQ handler was RFBI's frame
done handler.  dispc's IRQ framework was very dumb: you could only have
one handler, and the semantics of {request,free}_irq were odd, to say the
least.

The new framework allows multiple consumers to register arbitrary IRQ
masks.
