Instead of "fsl,lpa-widgets", I would like to add a common property 
"ignore-suspend-widgets" in sound-card-common.yaml file. So not only rpmsg
sound cards but also other sound cards which have such feature can use this
property to define wanted widgets ignoring suspend.
What do you think about that?
