[PATCH v2 1/2] dt-bindings: display: bridge: ti,sn65dsi83: Add dual-link video mode property

Add a new optional device tree property `ti,dual-link-video-mode`
to indicate that the bridge should configure the device for
dual-link LVDS video mode.

In dual-link configurations, some panels require the horizontal
timing parameters to be adjusted before programming them into
the device. In such cases, the horizontal timing values must be
divided by two when operating in dual-link mode.
