arm64: dts: qcom: sm8550: Flush RSC sleep & wake votes
[ Upstream commit 4b2c7ac8e469ab7f92e50c34ad4012a77e79d078 ]
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.
