brcm63xx: add preliminary support for 3.13

Add support for 3.13 as a development kernel. Mostly untested, only net
booted. If flashed may brick your router or kill your cat.

+Subject: [PATCH 32/53] MIPS: BCM63XX: append irq line number to
+ irq_{stat,mask}*
+
+The SMP capable irq controllers have two interupt output pins which are
+controlled through separate registers, so make the variables arrays.
