winsys/amdgpu: expand the slab allocation range to [256 B, 1 MB]

This increases the wasted memory to 140 MB for DeusExMD, still below
the original number. The advantage is that we now get 2 MB pages for more
buffers and fewer total buffers allocated by the kernel, enabling faster
GPU page translation and slightly lower kernel overhead.
