Bug description:
[Impact]
This bug cause "alsactl init" command unable to initialize mt8390-evk
correctly and print these error message:
```
ceqa@ubuntu:/home/ceqa$ alsactl init
alsa-lib main.c:761:(execute_sequence) unable to execute cset
'name='DP_OUT_MUX' Disconnect'
alsa-lib main.c:2373:(set_boot_user) Unable to execute boot sequence
Found hardware: "mt8390-evk" "" "" "" ""

```

2. Run `alsactl init` on MediaTek G700 device
3. alsactl print error message "unable to execute cset 'name='DP_OUT_MUX'
Disconnect'" and audio devices do not work.
Verify:
By applying this patch, alsactl does not print this error message and audio
devices work.

This patch fix the typo in ucm files, and it affects the device init process
on Mediatek Genio boards.
[ Other Info ]
There is a typo in
'd/p/0001-Add-initial-support-for-MediaTek-Genio-boards.patch'.
The name of the flag that controls the audio output of the DP port is
not 'DP_OUT_MUX'. It is 'DPTX_OUT_MUX'.
