dmaengine: at_hdmac: dt dma bindings update

Vinod,

This is the patch series that has already been sent by Ludovic. It is the part of the series that is dedicated to dmaengine. It is based on slave-dma/next. I plan to submit an additional patch through arm-soc as the .dtsi updates are dependent on a "cleanup" branch that is already stacked there.

This set of patches update the dt dma binding for at_hdmac since we need one more parameter. In order to keep backward compatibility, an existing cell will be used to add this parameter. Since the content of that cell will become a magic value due to the concatenation of the two parameters, it is time to use macros.

Thanks, best regards,

ARM: at91: dt: add header to define at_hdmac configuration
at_hdmac: add FIFO configuration parameter to DMA DT binding
