ARM: SoC cleanups and fixes for v4.7

Browse Source 
Traditionally we've had two separate branches for cleanups and non-critical
 bug fixes, but both of these got smaller with each release and the differences
 are rather unclear now, so it seems more appropriate to have a combined
 branch.
 
 The most notably change is for OMAP, which gets a small rework to simplify
 handling of the AUXDATA mechanism used on machines that are not completely
 DT based yet, along with other work that is used as preparation for dropping
 the legacy board files.

Pull ARM SoC cleanups and fixes from Arnd Bergmann:
 "Traditionally we've had two separate branches for cleanups and
  non-critical bug fixes, but both of these got smaller with each

  appropriate to have a combined branch.

  The most notable change is for OMAP, which gets a small rework to
  simplify handling of the AUXDATA mechanism used on machines that are
  not completely DT based yet, along with other work that is used as
  preparation for dropping the legacy board files"
