drm/amd/display: Adjust cursor position

[why & how]
When the commit 9d84c7ef8a87 ("drm/amd/display: Correct cursor position
on horizontal mirror") was introduced, it used the wrong calculation for
the position copy for X. This commit uses the correct calculation for that
based on the original patch.
