soundwire: amd: serialize amd manager resume sequence during pm_prepare
[ 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.
