PM / Domains: dt: Allow power-domain property to be a list of specifiers 



To be able to describe topologies where devices are partitioned across
multiple power domains, let's extend the power-domain property to allow
being a list of PM domain specifiers.

Required properties:

                   the power controller specified by phandle.

 - power-domains : A list of PM domain specifiers, as defined by bindings of

The node above defines a typical PM domain consumer device, which is located

inside a PM domain with index 0 of a power controller represented by a node

with the label "power".

The first example above defines a typical PM domain consumer device, which is

located inside a PM domain with index 0 of a power controller represented by a

node with the label "power".

In the second example the consumer device are partitioned across two PM domains,

the first with index 0 and the second with index 1, of a power controller that

is represented by a node with the label "power.
