arm-soc: driver specific changes

Browse source 
* Updates to the ux500 cpufreq code
 * Moving the u300 DMA controller driver to drivers/dma
 * Moving versatile express drivers out of arch/arm for sharing with arch/arm64
 * Device tree bindings for the OMAP General Purpose Memory Controller
 
 There is a simple conflict in drivers/cpufreq/dbx500-cpufreq.c, because
 the mach/id.h header and the cpu_is_u8500_family() function in it are
 now gone.
