drm/panel: Changes for v3.20-rc1

This contains the long-awaited drm_bridge series that makes Chromebooks
work for people. I had thought this would've been perfect by now, but
then I go and build test it and the first thing it does is yell about a
recursive dependency. I fixed that up because I was feeling bad for not
getting around to look at this earlier.

Biseds that there is new support for two more panels, a couple of fixup
patches to the Sharp LQ101R1SX01 dual-channel DSI panel driver and a
potential NULL pointer dereference fix.
