Allwinner H3 SPI controller has same architecture as A31.
So most configuration is identical except one thing - FIFO capacity.
A31 H3
------------------------------------
Number of controllers 4 2
Number of FIFO depth 128 64
Transfer bits 8 8
Register maps are sharable, so sun6i SPI driver is reusable with
device configuration.
Tested on Nano Pi M1 and SPI slave device is TI LP8860.
