drm/amd/display: fix link training regression for 1 or 2 lane
[why]
We have a regression that cause maximize lane settings to use
uninitialized data from unused lanes.
This will cause link training to fail for 1 or 2 lanes because the lane
adjust is populated incorrectly sometimes.
v2: fix build without CONFIG_DRM_AMD_DC_DCN (Alex)
