[PATCH 22/24] drm/amd/display: Adjust cursor position

[Tom Chung]

From: Rodrigo Siqueira <Rodrigo.Siqueira at amd.com>

[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.

Fixes: 9d84c7ef8a87 ("drm/amd/display: Correct cursor position on horizontal mirror")
