[PATCH xf86-video-ati 11/13] Use drmIoctl in drmmode_show_cursor

[Michel Dänzer]

From: Michel Dänzer <michel.daen...@amd.com>

This should be functionally equivalent to what drmModeSetCursor(2) do
behind the scenes, but allows for new tricks in following changes.

(Ported from amdgpu commit b344e1559e936046ef02c777fc4f6bcefa3830bc)
