mmc: Add support for enumerating MMC card in a given mode using mmc command
Add support for enumerating MMC card in a given mode using mmc rescan and
mmc dev commands. The speed mode is provided as the last argument in these
commands and is indicated using the index from enum bus_mode in
include/mmc.h. A speed mode can be set only if it has already been enabled
in the device tree.
