Bug description:
[Impact]
* On the Dell machines with multi function audio jack, the
headphone/headset can't output sound automatically, which is different
from ubuntu 18.04. The headphone/headset should be able to output
sound automatically after plugging in the audio jack.
[Test Case]
* On Tiger Lake platform
Reproduce step:
1. plug headphone/headset
2. open g-c-c sound to check
Expect result: The output device should switch to headphone or headset,
since headphone's priority is higher in ucm2 config.
Actual result: The output device is still internal speaker.
[Regression Potential]
* The change insert the ucm device by its priority, the potential
regression is low, since if the change is not working properly, the
side effect is that the order of ucm devices are wrong, and it won't
switch to the correct output device as expect, but user can still
config it manually.
[Other]
* This bug originates from an OEM private bug #1875597, then ubuntu users
reported 2 public bugs #1871329 and #1881659. The 2nd issue of #1871329
and the 1st issue of #1881659 have the same root cause as #1875597
* The root cause is the ucm2 conf defines 2 input devices: the Mic2 and
Headset MIC, and the pulseaudio parse the input device Headset MIC
first then Mic2, finally the audio jack is set to Mic2 mode, this make
the audio jack can't output sound anymore. To fix it, let the audio
jack set to Headset MIC mode by default (Headset MIC has higher
priority than Mic2 in the ucm2 conf), to do so, let pulseaudio send the
device event to module-switch-on-port-available by the order of
priority in the umc2.
