For now, acpi_irqchip_init() just introduced for GIC init, not for
APIC init for x86, and I don't see the usage in the near future.

I renamed it as acpi_irq_init() in the later patch, which
is called in irqchip_init() in drivers/irqchip/irqchip.c
to init irqchip when DT is not available.

This is not a nice way, but the kernel should stay functional
for each patch goes in, so I separate the patch to smaller one
for easy review under that rule, does it make sense?

Thanks
