Subject: [v1 2/3] dt-bindings: drm/bridge: ti-sn65dsi86: Document use-aux-backlight

If the panel connected to the bridge supports backlight control
using DPCD registers on the DisplayPort aux channel, setting
"use-aux-backlight" property in the bridge node will enable the
registration of a DP aux backlight device from the bridge driver.
