Nicholas Kazlauskas 922454c2e7 drm/amd/display: Fix duplicating scaling/underscan connector state
[Why]
These properties aren't being carried over when the atomic state.
This tricks atomic check and commit tail into performing underscan
and scaling operations when they aren't needed.

With the patch that forced scaling/RMX_ASPECT on by default this
results in many unnecessary surface updates and hangs under certain
conditions.

[How]
Duplicate the properties.

Fixes: 91b66c47ba ("drm/amd/display: Set RMX_ASPECT as default")
