drm/i915: add I915_BO_ALLOC_GPU_ONLY
If the user doesn't require CPU access for the buffer, then
ALLOC_GPU_ONLY should be used, in order to prioritise allocating in the
non-mappable portion of LMEM, on devices with small BAR.
v2(Thomas):
- The BO_ALLOC_TOPDOWN naming here is poor, since this is pure lies on
systems that don't even have small BAR. A better name is GPU_ONLY,
which is accurate regardless of the configuration.
