[PATCH 40/43] drm/amd/display: Cache cursor position.

[Harry Wentland]

From: Yongqiang Sun <yongqiang.sun at amd.com>

When programming cursor position after front end programmed,
if position is already set previously, it doesn't make sense
to program position with all 0.
Cache position and use the parameter after front end programming.
