Merge branch 'cleanup/dt-clock' into next/soc

Browse Source 
Merging in dt clock cleanup as a pre-req with some of the later SoC branches.

There are a handful of conflicts here -- some of the already merged SoC
branches should have been based on the cleanup but weren't.

In particular, a remove/add of include on highbank and two remove/remove
conflicts on kirkwood were fixed up.

* cleanup/dt-clock: (28 commits)
  ARM: vt8500: remove custom .init_time hook
  ARM: vexpress: remove custom .init_time hook
  ARM: tegra: remove custom .init_time hook
  ARM: sunxi: remove custom .init_time hook
  ARM: sti: remove custom .init_time hook
  ARM: socfpga: remove custom .init_time hook
  ARM: rockchip: remove custom .init_time hook
  ARM: prima2: remove custom .init_time hook

  ARM: exynos: remove custom .init_time hook
  ARM: dove: remove custom .init_time hook
  ARM: bcm2835: remove custom .init_time hook
  ARM: bcm: provide common arch init for DT clocks
  ARM: call of_clk_init from default time_init handler
  ARM: vt8500: prepare for arch-wide .init_time callback
