Subject: [PATCH 8/8] arm64: dts: qcom: sm8550: Flush RSC sleep & wake votes

The rpmh driver will cache sleep and wake votes until the cluster
power-domain is about to enter idle, to avoid unnecessary writes. So
associate the apps_rsc with the cluster pd, so that it can be notified
about this event.

Without this, only AMC votes are being commited.
