mmc: enable partition switch function for emmc
For emmc, it may have up to 7 partitions: two boot partitions, one user partition, one RPMB partition and four general purpose partitions. (Refer to JESD84-A44.pdf/page 154) As bootloader may need to read out or reflashing images on those different partitions, it is better to enable the partition switch with console command support. Also for partition would be restore to user partition(part 0) when CMD0 is used, so change mmc_init routine to perform normal initialization only once for each slot, unless use the rescan command to force init again.
