irqchip/apple-aic: Switch to irq_domain_create_tree and sparse hwirqs

Browse source

This allows us to directly use the hardware event number as the hwirq
number. Since IRQ events have bit 16 set (type=1), FIQs now move to
starting at hwirq number 0.

This will become more important once multi-die support is introduced in
a later commit.
