Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull arm-soc cleanups (part 2) from Olof Johansson:
 "More cleanups, continuing an earlier set with omap and samsung
  specific cleanups.  These could not go into the first set because they
  have dependencies on various other series that in turn depend on the
  first cleanups."

Fixed up conflicts in arch/arm/plat-omap/counter_32k.c due to commit
bd0493eaaf5c: "move read_{boot,persistent}_clock to the architecture
level" that changed how the persistent clocks were handled.  And trivial
conflicts in arch/arm/mach-omap1/common.h due to just independent
changes close to each other.
