soundwire: amd: fix for wake interrupt handling for clockstop mode

2024-05-02T14:35:32Z

[ Upstream commit 63dc588e7af1392576071a1841298198c9cddee3 ] When SoundWire Wake interrupt is enabled along with SoundWire Wake enable register, SoundWire wake interrupt will be reported when SoundWire manager is in D3 state and ACP is in D3 state. When SoundWire Wake interrupt is reported, it will invoke runtime resume of the SoundWire manager device. In case of system level suspend, for ClockStop Mode SoundWire Wake interrupt should be disabled. It should be enabled only for runtime suspend scenario. Change wake interrupt enable/disable sequence for ClockStop Mode in system level suspend and runtime suspend sceanrio.
