Subject: drm/omap: change supported_modes to an array
Git-commit: 18c0d6217a4898b9cae1b999e0dd37f8239ba0ae
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

enum omap_color_mode is a bitmask, so at the moment we present the
supported color modes as mask. To be able to move to fourccs, we need to
use an array to present the supported color modes.

As a first step towards fourccs, this patch changes the code to use an
array to store the enums.
