ARM: SoC non-critical bug fixes for 3.19

These are bug fixes for harmless problems that were not important
 enough to get fixed in 3.19. This contains updates to the MAINTAINERS
 file, in particular:
 
 - Ben Dooks stepped down as Samsung co-maintainer (thanks Ben for
   long years of maintaining this). Kukjin Kim, who has been
   doing the work de-facto by himself recently is now the
   only maintainer.
 - Liviu, Sudeep and Lorenzo from ARM now officially maintain the
   Versatile Express platform, which was orphaned (thanks for
 - Gregory Fong and Florian Fainelli help out on the Broadcom BCM7XXX
   platform
 - Ray Jui and Scott Branden are the future maintainers for the
   newly merged Broadcom Cygnus platform. Welcome!
 
 In terms of actual fixes, we have the usual set of OMAP bug fixes,
 which Tony Lindgren separates out well from the other OMAP changes,
 one really ep93xx regression fix against 3.11 that didn't make it for
 3.18, a few GIC changes from Marc Zyngier as a preparation for
 later rework (the current code is wrong in a harmless way), on
 Tegra regression and one samsung spelling fix.
