…arm/arm-soc

Pull ARM soc general cleanups from Olof Johansson:
 "This is a large branch that contains a handful of different cleanups:

   - Fixing up the I/O space remapping on PCI on ARM.  This is a series
     from Rob Herring that restructures how all pci devices allocate I/O
     space, and it's part of the work to allow multiplatform kernels.
   - A number of cleanup series for OMAP, moving and removing some
     headers, sparse irq rework and in general preparation for
     multiplatform.
   - Final removal of all non-DT boards for Tegra, it is now
     device-tree-only!
   - Removal of a stale platform, nxp4008.  It's an old mobile chipset
     that is no longer in use, and was very likely never really used
     with a mainline kernel.  We have not been able to find anyone
     interested in keeping it around in the kernel.
   - Removal of the legacy dmaengine driver on tegra

  + A handful of other things that I haven't described above."

Fix up some conflicts with the staging tree (and because nxp4008 was
removed)
