MIPS: ath79: fix a wrong IRQ number
The Ubiquiti XM board setup code uses an invalid IRQ number, because it if above of NR_IRQS. 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 -22 Preserve some IRQ numbers for the built-in IRQ controller of PCI host controllers in the AR71XX/AR724X SoCs, and use the correct IRQ number in the board setup code.
