video: dma-drm: Add modifier field to FormatMap

Browse source 
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.
