drm/amd/pm: inform SMU RLC status thus enable/disable DPM feature for vangogh
RLC is halted when system suspend/shutdown. However, due to DPM enabled, PMFW is
unaware of RLC being halted and will continue sending messages, which would
eventually cause an ACPI hang. Use the system_feature_control interface to
notify SMU the status of RLC (Normal/OFF) thus enable/disable DPM feature.
