On startup, setup_IO_APIC_irqs() will program all IOAPIC pins for ISA IRQs. Later when mp_map_pin_to_irq() is called, it just returns ISA IRQ number without programming corresponding IOAPIC pin. This patch consolidates the way to program IOAPIC pins for both ISA and non-ISA IRQs into mp_map_pin_to_irq() as below: 1) For ISA IRQs, mp_irqs array is used to map IOAPIC pin to IRQ and mp_irqdomain_map() is used to actually program the pin. 2) For non-ISA IRQs, irqdomain is used to map IOAPIC pin to IRQ, and mp_irqdomain_map() is also used to actually program the pin.
