drm/i915/bdw: Implement PPGTT clear range

Browse source

GEN8 PPGTT range clearing is very similar to GEN6 if we assume that our
PDEs are all valid, which they should be.

v2: Rebase on top of the address space refactoring.

v3: Rebase on top of the bool use_scratch addition to the clear_range interface.
