Subject: drm/omap: add new connector types
Git-commit: 564f88c1b975bd26ddcea961fd95f14108ef3f69
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

We have been using DRM_MODE_CONNECTOR_Unknown for many of our outputs
because there has not been a proper connector type for them.

We now have connector type for DPI so let's take it into use. At the
same time, add better connector types for the remaining outputs too.

This patch sets the following outputs to use the following connector
types:

DPI -> DPI
DBI -> DPI (MIPI DBI is very similar to DPI at the bus level)
SDI -> LVDS (SDI, TI Flatlink 3G, is a type of LVDS)
VENC -> SVIDEO or Composite
