drm/amdgpu: implement the allocation range (v3)
Pass a ttm_placement pointer to amdgpu_bo_create_restricted
add min_offset to amdgpu_bo_pin_restricted. This makes it
easier to allocate memory with address restrictions. With
this patch we can also enable 2-ended allocation again.
v2: fix rebase conflicts
v3: memset placements before using
