arm-soc: driver specific changes

* 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.
