dmaengine: dw: split dma-dw.h to platform and private parts
The introduced include/linux/dma/dw.h is going to contain the private
extensions and structures which are shared for dw_dmac users in the kernel.
Meanwhile include/linux/platform_data/dma-dw.h keeps only platform related data
types and definitions.
