[PATCH RFC v9 17/20] ARM: dts: imx6qdl-sabresd: Add support for TRULY TFT480800-16-E MIPI DSI panel

[Liu Ying]

The TRULY TFT480800-16-E panel is driven by the Himax HX8369A driver IC.
The driver IC supports several display/control interface modes, including
the MIPI DSI video mode and command mode.

v8->v9:
 * Rebase onto the imx-drm/next branch of Philipp Zabel's open git repository.

v7->v8:
 * None.

v6->v7:
 * None.

v5->v6:
 * None.

v4->v5:
 * Replace the bs[3:0]-gpios properties with the bs-gpios property.
   This addresses Andrzej Hajda's comment.

v3->v4:
 * None.

v2->v3:
 * None.

v1->v2:
 * To address Thierry Reding's comments, remove several unnecessary
   properties as they can be implied by the compatible string.
 * Fix the compatible string.
 * Remove the display-timings node from the panel node as it can be
   implied by the compatible string as well.
 * Remove the status property as it is unneeded.
