dt-bindings: soc: qcom,rpmh-rsc: Limit power-domains requirement
Certain platforms (such as Chrome SDM845 and SC7180 with a TF-A running
as secure firmware) do not have a OSI-mode capable PSCI implementation.
That in turn means the PSCI-associated power domain which represents the
system's power state can't provide enough feedback to the RSC device.
Don't require power-domains on platforms where this may be the case.
