From: Janine Hagemann <j.hagemann@xxxxxxxxx>
Add an optional property to change LVDS output voltage. This depends on
the connected display specifications. With this property we directly set
the LVDS_VCOM (0x19) register.
Better register property mapping would be quite tricky. Please check
bridge's datasheet for details on how register values set the LVDS
data lines and LVDS clock output voltage.
