Revert "drm/i915: Fix intel_dp_mst_compute_link_config"

This reverts commit c6266862.

Part of a series where patches were modified while applying to resolve
conflicts, leading to further conflicts between drm-misc-next and
drm-intel-next, resulting in build failures in drm-tip. To be applied
again on a baseline with drm-misc-next and drm-intel-next in sync.
