[Intel-gfx] [PATCH] drm/i915/selftests: Skip RPS tests on Ironlake (only IPS)

[Chris Wilson]

Since Ironlake uses intel_ips.ko for its dynamic frequency adjustment,
we do not have direct control over the frequency management so such
tests are defunct. Similarly, we can't check the gen6+ RPS registers on
Ironlake.

Hopefully this catches all the invalid tests now that Ironlake has
rejoined the dynamic GPU frequency club.
