[PATCH 2/2] drm/i915: Correct PPGTT total size

[Ben Widawsky <benjamin.widawsky@intel.com>]

Our code allows have a PPGTT that is smaller than the maximum size for
GEN6-GEN7. Though I don't think this actually ever occurs, the code may
as well work properly and more importantly look correct by using the
variable size instead of the HW max.
