Subject: [PATCH 4/4] arm64: dts: qcom: x1e80100: 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 committed.

Fixes: af16b00578a7 ("arm64: dts: qcom: Add base X1E80100 dtsi and the QCP dts")
