drm/i915: introduce intel_has_sagv()
And use it to move knowledge about the SAGV-supporting platforms from
the callers to the SAGV code.
We'll add more platforms to intel_has_sagv(), so IMHO it makes more
sense to move all this to a single function instead of patching all
the callers every time we add SAGV support to a new platform.
v2: Move I915_SAGV_NOT_CONTROLLED to the new function (Lyude).
