dt-bindings: power: rpmpd: Add sc8280xp RPMh power-domains

The sc8280xp has 13 power-domains controlled through the RPMh, document
the compatible and provide definitions for the power-domains - and their
active-only variants where applicable.

The SA8540p differs slightly in the power domains exposed, so add a
separate compatible for this, but reuse the constants to allow sharing
the DeviceTree source.
