Wayne Lin b5cd418f01 drm/amd/display: Validate mdoe under MST LCT=1 case as well 
[Why & How]
Currently in dm_dp_mst_is_port_support_mode(), when valdidating mode
under dsc decoding at the last DP link config, we only validate the
case when there is an UFP. However, if the MSTB LCT=1, there is no
UFP.

Under this case, use root_link_bw_in_kbps as the available bw to
compare.

Fixes: fa57924c76 ("drm/amd/display: Refactor function dm_dp_mst_is_port_support_mode()")
