Subject: [PATCH] USB-Audio: Add profile for MSI MPG X570S Carbon Max Wifi.

This patch depends on Linux 5.17.

This board features an Realtek ALC4080 chip. The various inputs and
outputs are distributed over multiple hardware devices:
* Input
 - hw:$card,0 loop back from speaker (called "Analog In")
 - hw:$card,1 line in at back panel
 - hw:$card,2 microphone from front AND back panel
* Output
 - hw:$card,0 speaker output at back panel (up to 7.1)
 - hw:$card,1 headerphone output at front panel
 - hw:$card,2 could not figure this one out
 - hw:$card,3 guessed S/PDIF output (sadly no way to test)

By default Mic and Line in are disabled. This confuses applications,
thus I made the profile enable them by default.

Without an UCM profile PulseAudio is not able to create output on
the front panel nor record any microphone input.
