Use two HW cursor buffers per CRTC
Switch to the other buffer when xf86_config->cursor changes. Avoids
these issues possible when re-using the same buffer:
* The HW may intermittently display a mix of the old and new cursor
images.
* If the hotspot changes, the HW may intermittently display the new
cursor image at the location corresponding to the old image's hotspot.
