Multimedia card device information structure.

A pointer to this structure must be passed to NutRegisterDevice() to bind this driver to the Nut/OS kernel. An application may then call /verbatim _open("MMC0:", _O_RDWR | _O_BINARY); /endverbatim to mount the first active primary partition with any previously registered file system driver (typically devPhat0).
