v1 -> v2:
* Adopted "arm,cortex-a53-pmu" compatible string (Sudeep)
* Adopted "arm,gic-400" compatible string (André, Sudeep)
* Adopted "arm,psci-0.2" compatible string and dropped functions (Sudeep)
* Squashed GIC reg extension patch, enlarged one (André)
* Squashed arch timer patch
* Added uart nodes and aliases (from Vega S95 .dtsi)
* Modeled cbus, aobus and apb
