ASoC: imx-rpmsg: Force codec power on in low power audio mode

Browse source

Low power audio mode requires binding codec still power on while Acore
enters into suspend so Mcore can continue playback music.

ASoC machine driver acquires DAPM endpoints through reading
"ignore-suspend-widgets" property from DT and then forces the path
between these endpoints ignoring suspend.

If the rpmsg sound card is in low power audio mode, the suspend/resume
callback of binding codec is overridden to disable the suspend/resume.
