No functional changes. Just clean up a conceptual mismatch. Based on feedback on the NUTMEG code in DC, the preferred_link_setting is meant to force the DP link to a specific setting, meaning both the link rate and lane count should be locked to an exact value. What NUTMEG needs is a lower bound on the link rate, which is not the same concept. Implement this as a HW workaround flag instead.
