Merge branch 'vexpress-dt-v3.3-rc4' of git://git.linaro.org/people/pawelmoll/linux into next/dt

* 'vexpress-dt-v3.3-rc4' of git://git.linaro.org/people/pawelmoll/linux: (573 commits)
  ARM: vexpress: Add Device Tree for V2P-CA15 core tile (TC1 variant)
  ARM: vexpress: Add Device Tree for V2P-CA9 core tile
  ARM: vexpress: Add Device Tree for V2P-CA5s core tile
  ARM: vexpress: Motherboard RS1 memory map support
  ARM: vexpress: Add Device Tree support
  ARM: vexpress: Use FDT data in platform SMP calls
  ARM: versatile: Map local timers using Device Tree when possible
  ARM: vexpress: Get rid of MMIO_P2V

This adds full device tree boot support for the versatile express
platform, as has been awaited for a long time.

Conflicts:
	arch/arm/mach-vexpress/core.h

The definition of AMBA_DEVICE was removed in one branch, and the
definition of MMIO_P2V was removed in the other branch.
