[PATCH 3/3] ARM: dts: keystone: Add minimal Keystone SOC device tree data

[Santosh Shilimkar]

Add minimal device tree data for Keystone2 based SOCs. Patch
contains mainly ARM related SOC data and nothing about EVM specific
yet.

I have seen some ongoing #include cleanups from Stephen Warren and cpu_node
updates from Lorenzo, but since am unaware of the dependencies, dts file is
aligned with the v3.10rcx ARM dts files. The changes are very trivial so
I can fix them quickly when they show up in linux-next.
