drm/i915/dp_link_caps: Add helper to reset link_caps state

Browse source

Add a helper to reset the link_caps state, removing all restrictions
except user-forced parameters, re-allowing all supported
configurations. Currently this only resets the maximum link limits,
but follow-up changes will also re-enable configurations previously
disabled on a per-configuration basis by fallback or other logic.
