This patchset adds support for the clock tree feeding the 4xCortex A53 cpu cluster.
This patchet does not handle clock changing, this will be added in a secondary patchset.
The CPU clock can either use the SYS_PLL for > 1GHz frequencies or use a couple of div+mux from 1GHz/667MHz/24MHz source with 2 non-glitch muxes.
The CPU clock must be switched to a safe clock while changing the clocks before the non-glitch muxes. Proper support will be added later.
In this patchset, clocks are set read-only.
