Merge branches 'msm/fixes-non-critical' and 'msm/cleanup' into next/dt

Merging in fixes and cleanup as prereqs to simplify merge conflicts.

* msm/fixes-non-critical:
  ARM: msm: Fix early debug uart mapping on some memory configs
  ARM: msm: io: Change the default static iomappings to be shared
  ARM: msm: io: Remove 7x30 iomap region from 7x00
  ARM: msm: Remove call to missing FPGA init on 8660

* msm/cleanup:
  ARM: msm: Remove uncompiled board-msm7x27
  ARM: msm: Remove unused acpuclock-arm11
  ARM: msm: dma: use list_move_tail instead of list_del/list_add_tail
  ARM: msm: Fix sparse warnings due to incorrect type
  ARM: msm: Remove unused idle.c
  ARM: msm: clock-pcom: Mark functions static
  ARM: msm: Remove msm_hw_reset_hook
