[PATCH xf86-video-ati] Only handle reflection in the driver with Xorg < 1.16

[michel@xxxxxxxxxxx (Michel Dänzer)]

From: Michel Dänzer <michel.daenzer@xxxxxxx>

Xorg doesn't handle the hardware cursor correctly in that case for
rotation and general transforms, and we can't force the SW cursor.

Fixes: f2bc882f1c10 ("Handle rotation in the driver also with Xorg
                      1.12-1.18")
