drm/i915: Protect older gen against intel_gt_init_powersave()
In the middle of intel_gt_init_powersave() we have an if-chain that ends
with a universal else clause to read gen6+ registers. Older platforms
like Pineview that end up here do not like those registers and may even
OOPS whilst reading them!
