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. Signed-off-by: Petr Štetiar <ynezz@true.cz>
