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. Signed-off-by:Alistair Francis <alistair.francis@xilinx.com> Suggested-by:
