drm/amd/display: Print Pcon FRL Link BW in Debug Message

Browse Source 
Under autonomous mode, source reads dpcd DP_PCON_HDMI_POST_FRL_STATUS
for the frl link status.

Without dsc passthrough, it serves as bw bottleneck on the entire link,
compared with the dp link from source to the converter where dsc is
available.
