[PATCH v2 12/12] ARM: dts: mvebu: Add a new set of registers to the PMSU node

[Gregory CLEMENT]

The Power Management Unit Service block also controls the Coherency
Fabric subsystem. This new set of registers is needed for the CPU idle
implementation for the Armada XP, it allows to enter in a deep CPU
idle state where the Coherency Fabric and the L2 cache are powerdown.
