[PATCH] ucm2: Rockchip: rk817: Fix Master Playback Volume

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

Correct the "Master Playback Volume" from a PlaybackMixerElem to a
PlaybackVolume. A user reported that without this change the hardware
volume would not change correctly. I've confirmed that when using
Pipewire the Pipewire volume and Master Playback Volume would change
independently, in some circumstances resulting in very low volume
that would be difficult to troubleshoot. By changing the Master
Playback Volume to PlaybackVolume this problem would no longer occur.
