dmaengine updates for 4.12-rc1

Browse source 
This time again a smaller update consisting of:
 
 - support for TI DA8xx dma controller and updates to the cppi driver
 - updates on bunch of drivers like xilinx, pl08x, stm32-dma, mv_xor, ioat,
   dmatest

- phy-names: Should be "usb-phy"
- dmas: specifies the dma channels
- dma-names: specifies the names of the channels. Use "rxN" for receive
and "txN" for transmit endpoints. N specifies the endpoint number.
Optional properties:
~~~~~~~~~~~~~~~~~~~~
- vbus-supply: Phandle to a regulator providing the USB bus power.
DMA
~~~
- compatible: ti,da830-cppi41
- reg: offset and length of the following register spaces: CPPI DMA Controller,
CPPI DMA Scheduler, Queue Manager
- reg-names: "controller", "scheduler", "queuemgr"
- #dma-cells: should be set to 2. The first number represents the
channel number (0 … 3 for endpoints 1 … 4).
The second number is 0 for RX and 1 for TX transfers.
