ARM: SoC platform updates 

In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
 C code changes for SoC platforms. This release cycle the diffstat is quite
 nice, in that we're removing 3x the amount of code that's being added.
 
 The main reason for this is that there's a removal of camera drivers for
 Freescale i.MX chips (driver was removed so the device registration isn't
 needed any more). There's also removal of display initialization code for OMAP
 that is no longer needed.
 
 The rest are mostly minor tweaks and cleanups; constification on Samsung
 platforms, cleanup of ux500 platform data, purge of other unused platform
 data/device seutp on i.MX and other good stuff.
 
 New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.
