dma: dw: split driver to library part and platform code To simplify the driver development let's split driver to library and platform code parts. It helps us to add PCI driver in future.

dmaengine: dw: move dw_dmac.h to where it belongs to There is a common storage for platform data related structures and definitions inside kernel source tree. The patch moves file from include/linux to include/linux/platform_data and renames it acoordingly. The users are also updated.

dmaengine: dw: introduce generic filter function The introduced filter function would be reused in the ACPI and DT cases since in those cases we have to apply mandatory data to the requested channel. Thus, patch moves platform driver to use it in that case. The function unlikely can't be used by users of the driver due to an implicit dependency to the dw_dmac_core module.
