Merge branch 'ux500/dt' into next/dt2

* ux500/dt:
  ARM: ux500: Provide local timer support for Device Tree
  ARM: ux500: Enable PL022 SSP Controller in Device Tree
  ARM: ux500: Enable PL310 Level 2 Cache Controller in Device Tree
  ARM: ux500: Enable PL011 AMBA UART Controller for Device Tree
  ARM: ux500: Enable Cortex-A9 GIC (Generic Interrupt Controller) in Device Tree
  ARM: ux500: db8500: list most devices in the snowball device tree
  ARM: ux500: split dts file for snowball into generic part
  ARM: ux500: combine the board init functions for DT boot
  ARM: ux500: Initial Device Tree support for Snowball
  ARM: ux500: CONFIG: Enable Device Tree support for future endeavours
  ARM: ux500: fix compilation after local timer rework

(adds dependency on localtimer branch, irqdomain branch and ux500/soc
branch)

Conflicts:
	arch/arm/mach-ux500/devices-common.c

This adds patches from Lee Jones, Niklas Hernaeus and myself to provide
initial device tree support on the ux500 platform. The pull request from
Lee contained some other changes, so I rebased the patches on top of
the branches that are actually dependencies for this.
