drm/i915: support 64K GTT pages for discrete cards
discrete cards optimise 64K GTT pages for local-memory, since everything
should be allocated at 64K granularity. We say goodbye to sparse
entries, and instead get a compact 256B page-table for 64K pages,
which should be more cache friendly. 4K pages for local-memory
are no longer supported by the HW.
v4: don't return uninitialized err in igt_ppgtt_compact
