drm/i915/dp_link_caps: Add helper to reset max link limits

Browse source

Add a helper to reset the link_caps::max_limits max link limits to the
maximum common supported rate and lane count.

This is needed by a follow-up change in the link training fallback code,
which temporarily resets max_limits before searching for a fallback
configuration.
