And while this alone would make a trivial fix, the H616 falls back to the A100 compatible string, so we have to now match the H616 compatible string explicitly against the description advertising 64K DMA blocks. As the A100 is now compatible with the D1 description, let the A100 compatible string point to that block instead, and introduce an explicit match against the H616 string, pointing to the old description. Also remove the redundant setting of clk_delays to NULL on the way.
