[0/6] ARM: mstar: Basic MPLL support

Message

This series adds support for the MPLL block that is present in
MStar/SigmaStar ARMv7 SoCs.

This block is intended to be set and forgotten about before
Linux is running so all it actually does it read the registers
and calculate what the output frequencies should be.

We only care about this block because there are upstream dividers,
gates, muxes etc that need something between the input crystal
and themselves to calculate their own rates.

I think this needs to be applied after the GPIO series[0] that
is currently inflight.
