Merge tag 'clksrc-cleanup-for-3.10-part2' of git://sources.calxeda.com/kernel/linux into late/clksrc

This is the 2nd part of ARM timer clean-ups for 3.10. This series has
the following changes:

- Add sched_clock selection logic to select the highest frequency clock
- Use full 64-bit arch timer counter for sched_clock
- Convert arch timer, sp804 and integrator-cp timers to CLKSRC_OF and
adapt all users to use clocksource_of_init

* tag 'clksrc-cleanup-for-3.10-part2' of git://sources.calxeda.com/kernel/linux:
  devtree: add binding documentation for sp804
  ARM: integrator-cp: convert use CLKSRC_OF for timer init
  ARM: versatile: use OF init for sp804 timer
  ARM: versatile: add versatile dtbs to dtbs target
  ARM: vexpress: remove extra timer-sp control register clearing
  ARM: dts: vexpress: disable CA9 core tile sp804 timer
  ARM: vexpress: remove sp804 OF init
  ARM: highbank: use OF init for sp804 timer
  ARM: timer-sp: convert to use CLKSRC_OF init
  OF: add empty of_device_is_available for !OF
  ARM: convert arm/arm64 arch timer to use CLKSRC_OF init
  ARM: make machine_desc->init_time default to clocksource_of_init
  ARM: arch_timer: use full 64-bit counter for sched_clock
  ARM: make sched_clock just call a function pointer
  ARM: sched_clock: allow changing to higher frequency counter

This has a nasty set of conflicts with the exynos MCT code, which was
moved in a separate branch, and then fixed up when merged in, but still
conflicts a bit here. It should have been sorted out by this merge though.
