MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches.

MIPS: ath79: simplify MISC IRQ handling The current code uses multiple if statements for demultiplexing the different interrupt sources. Additionally, the MISC interrupt controller has 32 interrupt sources and the current code does not handles all of them. Get rid of the if statements and process all interrupt sources in a loop to fix these issues.

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.

MIPS: Add header files reference with path prefix There are some common header files which are referenced locally with #includenext method, includenext is tricky method and only used on mips platform. This patech removes includenext method, replace it with defailed pathname prefix for header files. This patch passes to compile on all mips platform with defconfig, and is verified on my loongson64 box.
