Subject: [PATCH v2 9/9] arm64: dts: allwinner: h6: Move wakeup-capable IRQs to r_intc

All IRQs that can be used to wake up the system must be routed through
r_intc, so they are visible to firmware while the system is suspended.

For the H6, r_intc IRQ numbers are offset by 96 from the GIC IRQ
numbers.
