* dev - And instance of an MMC/SD interface. The MMC/SD hardware should
* be initialized and ready to use.

* registered as /dev/mmcsdN where N is the minor number
* slotno - The slot number to use. This is only meaningful for
* architectures that support multiple MMC/SD slots. This value must be
* in the range {0, ..., CONFIG_MMCSD_NSLOTS}.
* spi - And instance of an SPI interface obtained by called the
* appropriate xyz_spibus_initialize() function for the MCU "xyz" with
* the appropriate port number.
