Subject: [PATCH] ASoC: SOF: add a flag suspend_ignored for sof stream
Git-commit: 4cd933abd4820da7eefe672ff439b32d199a07be
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518
Add a suspend_ignored flag to snd_sof_pcm_stream that will be used to
decide if the corresponding FW pipeline should be kept active to perform
always on tasks when the system is entering the S0ix state.
