A significant amount of functions and other definitions are available through the public mmc card.h header file. Let's slim down this public mmc interface, as to prevent users from abusing it, by moving some of the functions/definitions to private mmc header files. This change concentrates on moving the functions into private mmc headers, following changes may continue with additional clean-ups.
