Recently introduced asynchronous probe on the MMC devices can shuffle
block IDs in the system. Pin them to values equal to the physical MMC bus
number to ease booting in environments where UUIDs are not practical.
Use newly introduced aliases for mmcblk devices from commit fa2d0aa96941
("mmc: core: Allow setting slot index via device tree alias").
