soundwire: amd: change the soundwire wake enable/disable sequence 



During runtime suspend scenario, SoundWire wake should be enabled and
during system level suspend scenario SoundWire wake should be disabled.

Implement the SoundWire wake enable/disable sequence as per design flow
for SoundWire poweroff mode.
