drm/i915: Enable IPS with only sprite plane visible too, v4.
This comment predates atomic, and I think with the way we currently track IPS, it's safe to enable this for the case we switch too. Changes since v1: - Keep IPS enabled when switching planes. Changes since v2: - Enable IPS when at least one plane is enabled. (Ville) Changes since v3: - Actually do what was advertised in v3, sigh!
