Subject[PATCH RFC 0/2] Make headphone work on Huawei Matebook D15
The headphone output at Huawei Matebook D15 is controlled by a separate
GPIO than the speaker. So, the es8336 boards logic need to handle two events:
one for the speaker switch and another one for the headphone.

Please notice that this is my first real incursion at SOC/SOF. While this is working
fine, I'm still struggling with some troubles with pipewire, which I believe are
due to UCM support, as, sometimes when pavucontrol starts, the playback stucks.
Also, sometimes the mixers won't change when jack plug/unplug is detected.

So, more debug is needed, and probably the UCM will also need to be closer to
the definitions that are used at ucm2/codecs/es8316/, as es8336 is a variant of

Anyway, let me submit this as as RFC, in order to get some feedback if this is
going at the right way to support the headphone switch event.
