get_mmc_num can be returned 0. Then if you use the "mmcinfo" command, it
can't print the mmc information.
If get_mmc_num is 0, it means that there is not mmc device.
So it added the get_mmc_curr_num() function for getting current device
number(index). And get_mmc_num() is returned the number of device.
This patch is only tested with mmc block..so i didn't touch the
blk-uclass.c.
