[PATCH xf86-video-amdgpu 3/3] Handle rotation in the driver also with Xorg 1.12-1.18

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

We cannot use the HW cursor in that case, but in turn we get more
efficient and less teary updates of rotated outputs.

(Ported from radeon commit f2bc882f1c1082bed9f496cfab6c8f07a76bc122)
