mmc: mmci: introduce dma_priv pointer to mmci_host
-Introduces dma_priv pointer to define specific
needs for each dma engine. This patch is needed to prepare
sdmmc variant with internal dma which not use dmaengine API.
-Moves next cookie to mmci host structure to share same cookie
management between all variants.
