    Initial LVDS support. You can resize but xrandr scale is still broken. Will fix scaling at a latter time but in general internal LVDS is supported.

    drm/ttm: fix delayed ttm_bo_cleanup_refs_and_unlock delayed handling
    
    Fix regression introduced by 85b144f860176
    "drm/ttm: call ttm_bo_cleanup_refs with reservation and lru lock held, v3"
    
    Slowpath ttm_bo_cleanup_refs_and_unlock accidentally tried to increase
    refcount on &bo->sync_obj instead of bo->sync_obj.
    
    The compiler didn't complain since sync_obj_ref takes a void pointer,
    so it was still valid c.
    
    This could result in lockups, memory corruptions, and warnings like
    these when graphics card VRAM usage is high:
