This patch adds single bitmap register support to intc. The current code only handles 16 and 32 bit registers where a set bit means interrupt enabled, but this is easy to extend in the future. The INTC_IRQ() macro is also added to provide a way to hook in interrupt controllers for FPGAs in boards or companion chips.
