drm/i915/gtt: Record the scratch pte

Browse source

Record the scratch PTE encoding upon creation rather than recomputing
the bits everytime. This is important for the next patch where we forgo
having a valid scratch page with which we may compute the bits and so
require keeping the PTE value instead.

v2: Fix up scrub_64K to use scratch_pte as well.
