drm/amd/display: Limit user regamma to a valid value
[ Upstream commit 3601d620f22e37740cf73f8278eabf9f2aa19eb7 ]
[Why]
For HDR mode, we get total 512 tf_point and after switching to SDR mode
we actually get 400 tf_point and the rest of points(401~512) still use
dirty value from HDR mode. We should limit the rest of the points to max
value.
[How]
Limit the value when coordinates_x.x > 1, just like what we do in
translate_from_linear_space for other re-gamma build paths.
