omapdrm changes for 4.12

Main changes include:

* Add support for render nodes.
* Refactor omapdss code to allow multiple DISPC implementations. This is pre-work for DSS6 support.
* Fix replication logic bug, which caused RGB565 fb to be shown too dark on a 24bit display.
* Improve detection of display stack readiness, which should remove the probe order issues.
* Link panel-dpi with its backlight, so that they are turned on/off in sync.
* Fix possibly incorrect setup of sync and data-enable signals.
* Get rid of DRM_OMAP_NUM_CRTCS config option.
