The I2C controller on the Allwinner hardware is actually a modified
Marvell controller. The difference is essentially register offsets
and a clock divider calculation based on a power of two. Also this
particular hardware needs a delay after sending a stop and before
reading the status register since apparently the data doesn't
propagate fast enough. This makes sxitwi(4) work on the Marvell
Armada 38x.
