[PATCH 1/7] dmaengine: Move AMD DMA driver to separate directory

[Basavaraj Natikar <Basavaraj.Natikar@amd.com>]

Currently, AMD PTDMA driver is single DMA driver supported and newer AMD
platforms supports newer DMA engine. Hence move the current drivers to
separate directory. This would also mean the newer driver submissions to
AMD DMA driver in the future will also land in AMD specific directory.
