drm/amd/display: Disable common modes for eDP 

[Why]
Common modes are added to eDP for compatibility in clone mode, but
not all panels support them.  Non-native modes were disabled in the past
but this caused problems because compositors didn't use scaling for non
native modes. Now non-native modes on eDP will enable the scaler by
default.

[How]
Check the connector type.  If the connector is eDP avoid adding common
modes.
