i915 wants to read out the PTE(s) populated by the BIOS/GOP
to verify that the framebuffer is in the correct location.
Introduce intel_gmch_gtt_read_entry() that reads out the
PTE and decodes it to a somewhat abstract form. For now
we just return the dma_addr, present bit, and local memory
bit. I didn't bother with the snoop bit/etc.
