[PATCH v2 0/2] clk: meson: g12a: Add CPU Clock support

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.

Changes since v1:
- moved to clk_regmap_gate_ro_ops for R/O gates
- added comments with datasheet field names
- moved pribate bindings changes to driver patch
- removed invalid PCIE IDs
