drm/amd/display: Enable 8k60hz mode on single display 

[Why]

8k60hz compliace test failing because we restrict it single memory
channels. Workaround by not restricting it on single displays.

[How]

Adding an additional check to DCN314 to restrict 8k60hz mode if it has
more than 1 display connected.
