[Intel-gfx] [PATCH 4/7] drm/i915/gem/ttm: Place new BOs in the requested region

[Jason Ekstrand]

__i915_gem_ttm_object_init() was ignoring the placement requests coming
from the client and always placing all BOs in SMEM upon creation.
Instead, compute the requested placement set from the object and pass
that into ttm_bo_init_reserved().
