Based on an idea from Dave, but cleaned up a bit.
We had multiple fields for essentially the same thing.
Now bo->base.size is the original size of the BO in
arbitrary units, usually bytes.
bo->mem.num_pages is the size in number of pages in the
resource domain of bo->mem.mem_type.
v2: use the GEM object size instead of the BO size
