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.
