[0/4] dmaengine: Add support Oxford Semiconductor OXNAS DMA Engine

Message

This serie adds support for the DMA engine found in Oxford Semiconductor SoCs,
notably in the OX810SE where it's heavily used for SATA transfers.

The driver was on my pipe since 2016 and a courageous person managed to get
the SATA driver work up mainline kernel with this driver, so I cleaned it up
in order to be upstreamed.

I plan to push the last patch through arm-soc when bindings is applied.
