Subject: [PATCH] LF-4175-6: ASoC: imx-rpmsg: add dummy headphone Jack for
pulseaudio
with rpmsg devices, there is not headphone plug event on A core side,
but pulseaudio would mute the headphone if there is not headphone
Jack event, so add dummy headphone Jack, which emulates the headphone
is plugged in always.
