i915: Map status page cached for chips with GTT-based HWS location.
This should improve performance by avoiding uncached reads by the CPU (the
point of having a status page), and may improve stability. This patch only
affects G33, GM45 and G45 chips as those are the only ones using GTT-based
HWS mappings.
