Subject: ASoC: wm8750: Make VREF a VMID instead of OUTPUT widget
Commit 04489eeb02a4 ("ALSA: wm8750: add missing VREF output") added the
previously missing VREF widget. And while adding the widget as OUTPUT widget
silences the error of the missing widget it should have rather been a VMID
widget.
The VREF widget is only used internally as a source for the VREF input of
the Out3 Mux. Selecting that input means that the path should be kept
powered up at the VREF/VMID voltage, but that there is no actual audio
signal. Using a VMID widget will do this, whereas using a OUTPUT widget will
simply cause the path to completely power down.
