soundwire: amd: serialize amd manager resume sequence during pm_prepare

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.
