The compat i915_drv.h contains things that aren't there in the original
i915_drv.h. Split out gem/i915_gem_object.h and i915_scheduler_types.h,
moving the corresponding pieces out, including FORCEWAKE_ALL to
intel_uncore.h.
Technically I915_PRIORITY_DISPLAY should be in i915_priolist_types.h,
but it's a bit overkill to split out another file just for
that. i915_scheduler_types.h shall do.
With this, the compat i915_drv.h becomes a strict subset of the
original.

shmem ensures the memory is cleared on allocation, however here we are
using TTM, which doesn't natively support shmem (other than for swap),
but instead just allocates normal system memory. And we only zero such
memory for userspace allocations. In the case of intel_fbdev we are
missing the memset_io() since display path incorrectly thinks object is
shmem based.

readq() is not available in 32bits and i915_gem_object_read_from_page()
is supposed to allow reading arbitrary sizes determined by the `size`
argument. Currently the only caller only passes a size == 8 so the
second problem is not that big. Migrate to calling
memcpy()/memcpy_fromio() to allow possible changes in the display side
and to fix the build on 32b architectures.
v2: Use memcpy/memcpy_fromio directly rather than using iosys-map with
the same size == 8 bytes restriction (Matt Roper)

As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there.
We do this by recompiling i915/display code twice.
Now that i915 has been adapted to support the Xe build, we can add
the xe/display support.
This initial work is a collaboration of many people and unfortunately
this squashed patch won't fully honor the proper credits.
But let's try to add a few from the squashed patches:
