ARM: SoC fixes for 4.4-rc

Browse Source 
This is the final small set of ARM SoC bug fixes for linux-4.4,
 almost all regressions:
 
 OMAP:		data corruption on the Nokia N900 flash
 Allwinner:	Two defconfig change to get USB working again
 ARM Versatile:	Interrupt numbers gone bad after an older bug fix
 Nomadik:	Crashes from incorrect L2 cache settings
 VIA vt8500:	SD/MMC support on WM8650 never worked
