drm/vmwgfx: Add kms helpers for dirty- and readback functions

Browse Source 
We need to make the dirty- and readback functions callable without a struct
drm_file pointer. We also need to unify the handling of dirty- and readback
cliprects that are now implemented in various places across the kms system,
som add helpers to facilitate this.
