Switch to using that driver.

The powerpc dts file does not have the xlnx,kind-of-intr property.
Instead of erroring out, give a warning instead. And attempt to
continue to probe the interrupt controller while assuming
kind-of-intr is 0x0 as a fall back.

The MIPS based xilfpga platform has the following IRQ structure
Peripherals --> xilinx_intcontroller -> mips_cpu_int controller
Add support for the driver to chain the irq handler

Now that the driver is generic and used by multiple archs,
get_irq is too generic.
Rename get_irq to xintc_get_irq to avoid any conflicts

The Xilinx AXI Interrupt Controller IP block is used by the MIPS
based xilfpga platform and a few PowerPC based platforms.
Move the interrupt controller code out of arch/microblaze so that
it can be used by everyone
