Merge tag 'msm-cleanup-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/cleanup

From David Brown:
Cleanups for MSM for 3.10

These are some patches for various parts of MSM that gradually bring
us closer to being part of single zimage.

* tag 'msm-cleanup-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm:
  ARM: msm: Remove unused cpu.h header file
  gpio: Make gpio-msm-v1 into a platform driver
  mmc: msm_sdcc: Remove unnecessary include
  ARM: msm: Move dma.h #defines that are private to dma.c
