From: Michel Dänzer <michel.daenzer@xxxxxxx>
commit 4349bd775cc8fd75cb648e3a2036a690f497de5c upstream.
We were storing viewport relative coordinates for AVIVO/DCE display
engines. However, radeon_crtc_cursor_set2 and radeon_cursor_reset pass
radeon_crtc->cursor_x/y as the x/y parameters of
radeon_cursor_move_locked, which would break if the CRTC isn't located
at (0, 0).

This is a backport for the 4.9 and possibly older stable branches.
BTW, this manual backport shouldn't have been necessary if this commit
and surrounding commits to the same file had been cherry-picked in the
same order as they are in mainline. Maybe any scripts used for that
could be improved accordingly.
