[PATCH v3] drm/dp_mst: Retrieve extended DPCD caps for topology manager

As per DP-1.3, First check DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT. If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 1, read the DP_DP13_DPCD_REV to get the faster capability. If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 0, read DP_DPCD_REV. Signed-off-by: Koba Ko Reviewed-by: Lyude Paul --- Changelo
