This reverts commit b84857c06ef9e72d09fadafdbb3ce9af64af954f.
5.10 stable contains 2 identical commits:
1. commit eb7bf11e8ef1 ("drm/i915/opregion: check port number bounds for SWSCI display power state")
2. commit b84857c06ef9 ("drm/i915/opregion: check port number bounds for SWSCI display power state")
Both commits add separate checks for the same condition. Revert the 2nd
redundant check to match upstream, which only has one check.
