mmc: sunxi-mmc: Fix A100 compatible description

commit 85b580afc2c215394e08974bf033de9face94955 upstream.

It turns out that the Allwinner A100/A133 SoC only supports 8K DMA
blocks (13 bits wide), for both the SD/SDIO and eMMC instances.
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.
