i915/i915_pm_rc6_residency: Suppress idle leakage warning on older arches
Sandybridge's rc6p while only consuming half the power of rc6, still
consumes a non-zero power. It appears Ivybridge was the first platform
to achieve negligible power draw (at least reported by the GPU) while in
rc6p (and later platforms in rc6). So exclude Sandybridge from
generating a warning as we have no hope of fixing.
