Subject: [PATCH 00/14] dmaengine: dma350: Support slave_sg, cyclic and DMA-250

This series firstly does some cleanups, then add support of
device_prep_slave_sg and device_prep_dma_cyclic to DMA-350. 

Lastly, add support for ARM DMA-250 IP. Compared with DMA-350, DMA-250
is a simplified version. They share many common parts, but they do
have difference. Add DMA-250 support by handling their difference by
using different device_prep_slave_sg, device_prep_dma_cyclic and
device_prep_dma_memcpy. DMA-250 doesn't support device_prep_dma_memset.
