If we just apply this patch, then this KConfig option is unused. Can we
please squash this into patch 3/4?

There is a finite list of supported options for this. Can we please
document all of them so that users know what is valid and what not?
If so, we can drop the "etc" part in the help string.

When FASTBOOT_FLASH_BLOCK=="mmc", how is FASTBOOT_FLASH_BLOCK_DEVICE_ID
different from FASTBOOT_FLASH_MMC_DEV?

If they are similar, are we sure this symbol really needed?
