Jiang Liu b5dc8e6c21 x86/irq: Use hierarchical irqdomain to manage CPU interrupt vectors
Abstract CPU local APIC as an interrupt controller and create an
irqdomain for it to manage CPU interrupt vectors. It's the base to
enable hierarchical irqdomains on x86 systems. 

The final irqdomain hierarchy will look like this:

IOAPIC domain    ----|
MSI/MSI-x domain ----> [Interrupt Remapping domain] -> CPU vector domain
HPET_IRQ domain  ----|                                         ^
                                                               |
DMAR domain      ----------------------------------------------|
HT_IRQ domain    ----------------------------------------------|
