[Impact]
HDMI/DP audio isn't working on Dell's USB-C dock.

[Fix]
Leave Maud/Naud as is, since the hardware programmed the right value
already.

[Test]
HDMI/DP audio always comes out from the USB-C dock after the fix is
applied.

[Where problems could occur]
DP/HDMI audio _might_ stop working.

However, the commit has been in mainline and OEM kernel for quite a
while, the absence of regression report is a good sign.
