Subject: [PATCH v5 1/6] dt-bindings: power: Convert mti,mips-cpc to DT schema

It's a Cluster Power Controller embedded into the MIPS IP cores.
Currently the corresponding dts node is supposed to have compatible
and reg properties.

Changelog prev:
- Reword the changelog summary - use shorter version.
- Lowercase the example hex'es.

Changelog v5:
- Consider address and size cells being <1> by default for the examples.
