Microblaze: Convert Microblaze-pic handling to GPIOs
This patch uses inbound GPIO lines (IRQ and FIR) for
interrupts instead of using the old pic_cpu method,
which doesn't correspond to real hardware.
This creates the CPU's inbound IRQ and FIR GPIO lines and
updates the Microblaze boards to use this new method.
