Subject: [PATCH AUTOSEL 6.6 221/294] soundwire: amd: change the soundwire wake enable/disable sequence

From: Vijendar Mukunda <Vijendar.Mukunda@....com>

[ Upstream commit dcc48a73eae7f791b1a6856ea1bcc4079282c88d ]

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.
