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.
