dt-bindings: drm/bridge: ti-sn65dsi83: Add properties for ti,lvds-vod-swing

Add properties which can be used to specify LVDS differential output
voltage. Since this also depends on near-end signal termination also
include property which sets this. LVDS differential output voltage is
specified with an array (min, max), which should match the one from
connected device.
