Yes, please

For Milk-V Jupiter, it has emmc slot despite plug the module in or not,
so it make sense to name it as mmc1, in other words, the board do support
emmc in the hardware level

For future board, if the board has no emmc feature design in, then I'd 
be fine with name it as mmc0 or mmc1, shouldn't be much difference..
