mmc: sh_mmcif: remove unneeded struct sh_mmcif_dma, prepare to shdma conversion
Now that all users have been updated to use the embedded in struct
sh_mmcif_plat_data DMA slave IDs, struct sh_mmcif_dma is no longer needed
and can be removed. This also makes preparation to the shdma base library
conversion easier.
