Petr Štetiar 5f2ff607e2 uboot-sunxi: a64: allow booting directly from eMMC
Current boot script uses hardcoded bootdevice, which allows booting from
SD card only, so this patch allows booting directly from eMMC as well.
While at it, replace fixed root device with more flexible UUID based
probing, so from now on probing order of MMC device doesn't matter.
