drm/amd/display: Enable HW rotation
[Why] HW rotation is not enabled. Calculations for cursor rotation are wrong for the values passed to set_cursor_position. [How] Swap Src rect and height and vertically mirror surface for the correct surface rotation direction. Cursor position is rotated according to angle. Offset calculations are tweaked for non-rotated cursor hotspot and width/height.
