Add support for MT8365 EVK with SOF enabled. When SOF is disabled, the "HiFi" use case is used; when SOF is enabled, the "SOF" use case is used. The main difference compared to the UCM with SOF disabled is the device number for playback and capture, which now uses the PCMs for SOF instead. Define these parameters as variables for each case (with and without SOF), and move the common initialization to init.conf, so the UCM can be shared by both configurations.

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
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.
