winsys/radeon: restore the old r600g winsys memory characteristics.

Browse source 
Use VRAM for static and immutable buffers. This restores the
recently removed r600g winsys behaviour for memory locations.
This also improoves rendering times on the gpu for some
OpenSceneGraph based test cases by about 15%.
