Sometimes, there would be a need to exchange data between DMA provider and DMA client which are very specific to DMA driver of the SoC/platform and are not generic enough to be put into struct dma. Therefore, introduce dma_get_cfg() interface to get DMA provider specific data from client device. Clients can use unique configuration ID flags to get different configuration data from DMA driver.
