Subject: [RFC PATCH v2 2/2] soc: qcom: rmphpd: Call the genpd unused power off sync state callback

Genpd provides a generic sync state callback for disabling unused
domains for a specific provider identified by its device. Call that
generic callback from the existing sync state callback in order to
disable all RPMh PD unused domains when all the consumers have probed.
