[0/3] Sun8i NAND DMA support

Message

Hello,

This series improves the NAND throughput on sun8i platforms by adding
DMA support. This increase comes from the ECC pipelining feature.

Because NAND DMA handling has changed between A10+ and A33 SoCs, we
must introduce a new compatible. DT is updated with this new
compatible in addition with the usual DMA properties.

Tested on an A33-Olinuxino.

Thanks,
Miquèl
