Pull ARM SoC cleanups from Arnd Bergmann:
 "This contains cleanups as preparation for other branches adding new
  features, we pulled 16 branches for 9 platforms into this one.

  Most notable here is the removal of support for ATAGS based OMAP4
  systems.  Since all OMAP4 machines are fully functional with DT based
  booting in 3.10, we can remove a lot of code here.

  Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,
  which means we need no machine descriptors in a lot more cases and can
  boot additional machines by just having the respective device drivers
  enabled."
