  direction removal and random updates to bunch of drivers.

  Summary:
   - New driver for UniPhier MIO DMA controller
   - Remove R-Mobile APE6 support
   - Sprd driver updates and support for cyclic link-list
   - Remove dma_slave_config direction usage from rest of drivers
   - Minor updates to dmatest, dw-dmac, zynqmp and bcm dma drivers"
