MIPS: ATH79: Add irq chip ar7240-misc-intc

The ar7240 misc irq chip use ack handler
instead of ack_mask handler. All new ath79 chips use
the ar7240 misc irq chip

- #interrupt-cells : Specifies the number of cells needed to encode interrupt

Compatible fallback depends on the SoC. Use ar7100 for ar71xx and ar913x,
use ar7240 for all other SoCs.
Please refer to interrupts.txt in this directory for details of the common
Interrupt Controllers bindings used by client devices.
