drm/amd/display: Disable common modes for LVDS
[Why]
Common modes are added to LVDS 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 LVDS will enable the scaler by
default.
[How]
Check the connector type. If the connector is LVDS avoid adding common
modes.
