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

commit 8e57ec613df7d6bfa8ffe7512290c5415ebb8657 upstream.

We were storing viewport relative coordinates. However, crtc_cursor_set2
and cursor_reset pass amdgpu_crtc->cursor_x/y as the x/y parameters of
cursor_move_locked, which would break if the CRTC isn't located at
(0, 0).
