[PATCH v2 0/5] Add CPU clock support for Armada 7K/8K

[Gregory CLEMENT]

Hello,

This is the second version of a series allowing to manage 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.

Changelog v1->v2:
 - Header cleanup
 - Use unsigned int instead of it for cluster member of the ap_cpu_clk struct
 - Use clk_hw instead of clk
 - Use regmap_read_poll_timeout
 - Use for_each_of_cpu_node
 - Remove unnecessary WARN_ON()
 - Remove headers from armada_ap_cp_helper.h
 - Few other minor cleanup
