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.
