drm/amd/display: limit timing for single dimm memory

Browse source

[Why]
1. It could hit bandwidth limitdation under single dimm
memory when connecting 8K external monitor.
2. IsSupportedVidPn got validation failed with
2K240Hz eDP + 8K24Hz external monitor.
3. It's better to filter out such combination in
EnumVidPnCofuncModality
4. For short term, filter out in dc bandwidth validation.

[How]
Force 2K@240Hz+8K@24Hz timing validation false in dc.
