A GST_VIDEO_FORMAT_* could be mapped to only one pair of DRM_FORMAT_* and DRM_FORMAT_MOD_*. Until now only DRM_FORMAT_MOD_LINEAR was used. To be able to add other modifiers add a modidier field in struct FormatMap. Create a helper functions the allow turning a GstVideoFormat into a pair of DRM fourcc and modifier and vis-versa.
