[ Upstream commit 03837341790039d6f1cbf7a1ae7dfa2cb77ef0a4 ]
During pm_prepare callback, pm_request_resume() delays SoundWire manager D0 entry sequence. Synchronize runtime resume sequence for amd_manager instance prior to invoking child devices resume sequence for both the amd power modes(ClockStop Mode and Power off mode). Change the power_mode_mask check and use pm_runtime_resume() in amd_pm_prepare() callback.
