[RFC PATCH 4/4] dt-bindings: Add support for devices with multiple PM domains

[Jon Hunter]

Now that the generic PM domain framework supports consumers that can
control multiple PM domains, update the device-tree binding for generic
PM domains to state that one or more PM domain is permitted for a
device.

 Optional properties:

    Some power domains might be powered from another power domain (or have
    other hardware specific dependencies). For representing such dependency
    a standard PM domain consumer binding is used. When provided, all domains
