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! (Ville, CI)
