Merge branch 'for-armsoc' of git://git.linaro.org/people/rmk/linux-arm

Pull #1 ARM updates from Russell King:
 "This one covers stuff which Arnd is waiting for me to push, as this is
  shared between both our trees and probably other trees elsewhere.

  Essentially, this contains:
   - AMBA primecell device initializer updates - mostly shrinking the
     size of the device declarations in platform code to something more
     reasonable.
   - Getting rid of the NO_IRQ crap from AMBA primecell stuff.
   - Nicolas' idle cleanups.  This in combination with the restart
     cleanups from the last merge window results in a great many
     mach/system.h files being deleted."

Yay: ~80 files, ~2000 lines deleted.
