Revert "drm/i915/opregion: check port number bounds for SWSCI display power state"

This reverts commit b84857c06ef9e72d09fadafdbb3ce9af64af954f.

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")
