ucm2: Qualcomm: add Fairphone (Gen. 6) (milos) profile 
Add a UCM profile for the Fairphone (Gen. 6) (SM7635 "milos") as used
on postmarketOS mainline: Speaker (2x Awinic AW88261 on Senary MI2S,
MultiMedia1 playback) and the handset microphone (WCD9378 AMIC1 via the
TX macro, MultiMedia2 capture). Tested on the phone with PipeWire in a
Plasma Mobile session.

The layout follows conf.d/qcm6490: real files under
Qualcomm/milos/Fairphone-Gen6/, a card-name symlink in conf.d/milos/.
Content is identical to the files tested on the device except the
verb File path, which follows the new location.

ALSA Use Case Manager configuration

Installation

Copy the ucm and ucm2 trees to the alsa-lib configuration directory (usually located in /usr/share/alsa) including symlinks. The files in the package root directory (README.md, LICENSE and VERSION) files are extra (only informational).

Example:

tar xvjf alsa-ucm-conf-1.2.6.2.tar.bz2 -C /usr/share/alsa --strip-components=1 --wildcards "*/ucm" "*/ucm2"

The latest configuration can be obtained with those commands:

curl -L -o alsa-ucm-conf.tar.gz https://github.com/alsa-project/alsa-ucm-conf/archive/refs/heads/master.tar.gz
tar xvzf alsa-ucm-conf.tar.gz -C /usr/share/alsa --strip-components=1 --wildcards "*/ucm" "*/ucm2"

State file

Some values may be set only one time by UCM and then they are saved to the global ALSA sound state file. Please, make sure that this state is cleared, if you have an issue.

Commands for standard systemd setup (relogin is required):

systemctl stop alsa-state
rm /var/lib/alsa/asound.state
systemctl start alsa-state

Validation

Validate UCM configuration

The UCM configurations are automatically validated using the UCM validator available at https://github.com/alsa-project/alsa-tests/tree/master/python/ucm-validator .

If you create a pull request for new hardware, please, add also the alsa-info.sh output to emulate this hardware in the UCM validator.
