mmc: atmel-mci: conform to DMA-API
Fixes the following:
- It is perfectly legal for the dma_map_sg() to return fewer
entries than were passed in.
- Supply the returned numer of (possibly coalesced) entries to
the device_pre_slave_sg() function.
- Use the proper original sg_len when unmapping the sglist
in the error path.
