[PATCH v3 11/11] ARM: mvebu: add SMP support in the Armada 38x device tree

[Thomas Petazzoni]

This commit improves the Armada 38x Device Tree to add the CPU reset
and PMSU Device Tree nodes as well as the declaration of the enabling
method for the CPUs. These are needed to get SMP working on Armada 38x
platforms.
