json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

There's no point allowing anything else but "psci" for the corresponding
nodename of the PSCI node, so let's make this an explicit requirement.
Moreover, let's also prevent additional properties, which also allows a
better verification of the "patternProperties" bindings for subnodes.

The hierarchical topology with power-domain should be described through
child nodes, rather than as currently described in the PSCI root node. Fix
this by adding a patternProperties with a corresponding reference to the
power-domain DT binding.
Additionally, update the example to conform to the new pattern, but also to
the adjusted domain-idle-state DT binding.

While converting to the json-schema, let's also take the opportunity to
further specify/clarify some more details about the DT binding.
For example, let's define the label where to put the states nodes, set a
pattern for nodename of the state nodes and finally add an example.

Several DT references got broken due to txt->yaml conversion.
Those are auto-fixed by running:

Update PSCI DT bindings to allow to represent idle states for CPUs and the
CPU topology, by using a hierarchical layout. Primarily this is done by
re-using the existing DT bindings for PM domains [1] and for PM domain idle
states [2].
Let's also add an example into the document for the PSCI DT bindings, to
clearly show the new hierarchical based layout. The currently supported
flattened layout, is already described in the ARM idle states bindings [3],
so let's leave that as is.
