[0/6] Add CPU clock support for Armada 7K/8K

Hello,

This series allows to mange the cpu clock for Armada 7K/8K. For these
SoCs, the CPUs share the same clock by cluster, so actually the clock
management is done at cluster level.

As for the other Armada 7K/8K clocks it is possible to have multiple
AP so here again we need to have unique name: the purpose of the second
patch is to share a common code which will be used in 3 drivers.

The last 2 patch enable the driver at dt and platform level and will
be applied through the mvebu subsystem.

Gregory
