x86/uv: Use hierarchical irqdomain to manage UV interrupts

Enhance UV code to support hierarchical irqdomain, it helps to make
the architecture more clear.

We construct hwirq based on mmr_blade and mmr_offset, but mmr_offset
has type unsigned long, it may exceed the range of irq_hw_number_t. So
help about the way to construct hwirq based on mmr_blade and
mmr_offset is welcomed!

Folded a patch from Dimitri Sivanich <[email protected]> to fix a bug
on UV platforms, please refer to:
