Add basic clock driver and pmu compatible support for the
Axis ARTPEC-9 SoC which contains 6-core Cortex-A55 CPU
and other several IPs. This SoC is an Axis-designed chipset
used in surveillance camera products.

This ARTPEC-9 SoC has a variety of Samsung-specific IP blocks and
Axis-specific IP blocks and SoC is manufactured by Samsung Foundry.

This patch series includes below changes:
- CMU (Clock Management Unit) driver and its bindings (patch #1 to #3)
- PMU bindings (patch #4)

The patch series has been tested on the ARTPEC-9 EVB with
Linux Samsung SoC tree (for-next branch) and intended
to be merged via the `arm-soc` tree.

---
Changes in v2:
- Decouple the device tree related patches which was present in v1 (Patch #5 to #7)
  Device tree related patches will be sent in separate series.
- Fix the division issue (in arm target) reported by kernel test in patch #2
