i915: support 8xx desktop cursors
For some reason we never added 8xx desktop cursor support to the kernel. This patch fixes that. [krh: Also set the size on pre-i915 hw.] Tested-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>
