ALSA: usb-audio: add mapping for MSI MAG X570S Torpedo MAX.

[ Upstream commit 4ddef9c4 ]

The USB audio device 0db0:a073 based on the Realtek ALC4080 chipset
exposes all playback volume controls as "PCM". This makes
distinguishing the individual functions hard.
The mapping already adopted for device 0db0:419c based on the same
chipset fixes the issue, apply it for this device too.
