MIPS: ath79: add PCI IRQ handling code for AR724X SoCs
The PCI Host Controller of the AR724x SoC has a
built-in IRQ controller. The current code does
not supports that, so the IRQ lines wired to this
controller are not usable. This leads to failed
'request_irq' calls:
ath9k 0000:00:00.0: request_irq failed
ath9k: probe of 0000:00:00.0 failed with error -89
This patch adds support for the IRQ controller
in order to make PCI IRQs work.
