x86/irq: Convert IOAPIC to use hierarchical irqdomain interfaces
Convert IOAPIC driver to support and use hierarchical irqdomain
interfaces. It's a little big, but would break bisecting if we split
it into multiple patches.
Fold in a patch from Andy Shevchenko <andriy.shevchenko@linux.intel.com>
to make it bisectable.
