Zack Rusin 88685c3e7d drm/vmwgfx: Enable DMA mappings with SEV 
commit 4c08f01934 upstream.

Enable DMA mappings in vmwgfx after TTM has been fixed in commit
3bf3710e37 ("drm/ttm: Add a generic TTM memcpy move for page-based iomem")

This enables full guest-backed memory support and in particular allows
usage of screen targets as the presentation mechanism.
