drm/amd/display: fix cursor offset on rotation 180
[ Upstream commit 737222cebecbdbcdde2b69475c52bcb9ecfeb830 ]
[why & how]
Cursor gets clipped off in the middle of the screen with hw
rotation 180. Fix a miscalculation of cursor offset when it's
placed near the edges in the pipe split case.
Cursor bugs with hw rotation were reported on AMD issue
tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247
The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@xxxxxxx/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.
