mixer-control: consolidate port finding and setting with/without ucm

Browse Source 
Recently Intel added a new audio driver in the Linux kernel, it is
called sof driver. This driver is needed on the laptops which
connects the digital mic to the PCH instead of the codec. To make the
sof driver work with pulseaudio, the ucm is mandatory.

With the ucm, the multi-function audio jack has different port names
in the pulseaudio from the one without ucm, these are the port names
with the ucm:
[In] Mic1: Digital Microphone
[In] Mic2: Headphones Stereo Microphone
[In] Headset: Headset Mono Microphone
[Out] Headphones: Headphones
[Out] Speaker: Speaker

To make the audio device selection work on the machines using the ucm,
the pulseaudio introduces a change to add 2 new members in the device
port structure from the PA_PROTOCOL_VERSION=34, with these 2 members'
help, we could consolidate the port finding and setting for both with
ucm and without ucm.

And this patch maintains the backward compatibility with the
PA_PROTOCOL_VERSION < 34.

TODO: Check if we still need this with the changed PA port names
In PulseAudio ports will show up with the following names:
In PulseAudio without ucm, ports will show up with the following names:
Headphones - analog-output-headphones
Headset mic - analog-input-headset-mic (was: analog-input-microphone-headset)
Jack in mic-in mode - analog-input-headphone-mic (was: analog-input-microphone)
In PulseAudio with ucm, the ports name depends on the ucm, with the current
ucm2, the ports will show up with the following names:
Headphones - [Out] Headphone
Headset mic - [In] Headset
Jack in mic-in mode - [In] Mic2
However, since regular mics also show up as analog-input-microphone,
we need to check for certain controls on alsa mixer level too, to know
if we deal with a separate mic jack, or a multi-function jack with a
