drm/i915/dp_link_caps: Re-enable link configurations after a link reset

Browse Source 
Re-enable link configurations after the link is reset via a call
to intel_dp_link_caps_reset(), allowing a subsequent modeset to
use all the link configurations of a sink newly connected or an already
connected sink changing its capabilities.
