Subject: drm/i915: Add PTE encoding function to the gtt/ppgtt vtables.

drm/i915: Add PTE encoding function to the gtt/ppgtt vtables.

Sandybridge/Ivybridge, Bay Trail, and Haswell all have slightly
different page table entry formats.  Rather than polluting one function
with generation checks, simply use a function pointer and set up the
correct PTE encoding function at startup.

v2: Move the gen6_gtt_pte_t typedef to i915_drv.h so that the function
    pointers and implementations have identical signatures.  Also remove
    inline keyword on gen6_pte_encode.  Both suggested by Jani Nikula.
