ASoC: imx-es8328: Map missing jack kcontrols

This driver does not properly map jack pins to kcontrols that PulseAudio
and PipeWire need to handle jack detection events. It seems to have a
single detection GPIO pin used to report everything as a Headset. But it
has widgets for Headphone and Mic Jack, so expose both to userspace as
kcontrols.
