dt-bindings: power: add Amlogic Everything-Else power domains bindings
Add the bindings for the Amlogic Everything-Else power domains, controlling the Everything-Else peripherals power domains. The bindings targets the Amlogic G12A and SM1 compatible SoCs, support for earlier SoCs will be added later.
