dmaengine: sun6i: Enable additional burst lengths/widths on H3

Browse source

The H3 supports bursts lengths of 1, 4, 8 and 16 transfers, each with
a width of 1, 2, 4 or 8 bytes.

The register value for the the width is log2-encoded, change the
conversion function to provide the correct value for width == 8.
