drm/i915: Don't clobber the GTT when it's within stolen memory
commit f1e1c2129b79cfdaf07bca37c5a10569fe021abe upstream.
On most gen2-4 platforms the GTT can be (or maybe always is?)
inside the stolen memory region. If that's the case, reduce the
size of the stolen memory appropriately to make make sure we
don't clobber the GTT.
v2: Deal with gen4 36 bit physical address
