drm/amd/display: only include FEC overhead if both asic and display support FEC
[why]
Some asics don't support FEC but FEC overhead is added into link
bandwidth calculation by mistake. This causes certain timing cannot be
validated.
[how]
Only include FEC overhead if both asic and display support FEC.
