x86/irq: Prepare IOAPIC interfaces to support hierarchical irqdomains
Introduce helper functions to manipulate struct irq_alloc_info for
IOAPIC. Also add an extra parameter to IOAPIC interfaces to prepare
for hierarchical irqdomain. Function mp_set_gsi_attr() will be removed
once we have switched to hierarchical irqdomains.
