A series of patches to fix mode programming for the Lontium lt9611
DSI-to-HDMI bridge (found e.g. on the Thundercomm RB3/Dragonboard845c
platform).

Changes since v2:
 - Rewrote mode_valid callback to be more explicit.

Changes since v1:
 - Fixed the double-DSI check to look for the lt9611->dsi1_node rather
   than lt9611->dsi1, modesetting happens before lt9611->dsi1 is set.

 - Added full dual-DSI support, properly enabling the 4k modes on RB3.
