drm/i915: Probe whether SAGV works on pre-icl

Browse source

Instead of leaving the SAGV enable/disable to the first commit
let's try to disable it first thing to see if we can do it or
not (disabling SAGV is a safe thing to at any time). This avoids
running the code in this funny intermediate state where we don't
know if SAGV is available or not.
