Subject: [PATCH v1 1/2] dt-bindings: display: bridge: sn65dsi83: Add DSI video mode

From: Francesco Dolcini <francesco.dolcini@...adex.com>

SN65DSI8[34] device supports burst video mode and non-burst video mode
with sync events or with sync pulses packet transmission as described in
the DSI specification.

Add property to select the expected mode, this allows for example to
select a mode that is compatible with the DSI host interface.
