vaallocator: use GstVideoInfoDmaDrm for dmabuf setup

Browse source 
Instead of guessing the DRM format and modifier, pass a DRM video info to
gst_va_dmabuf_memories_setup().

Still, it checks for the DRM parameters in DRM info, if they are not available,
as in the case of V4L2 buffers, the part of the video info is used.

This is an API breakage, but since the plugin is still in stage, it's still
allowed.
