ARM: SoC cleanups for 3.17

Browse source 
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.
