board/orangepi/orangepi-zero: using PARTUUID to identify root filesystem

Browse Source 
The mmc block device number can vary, so passing a mmc block device to
specify the location of the rootfs is not a reliable
approach. Instead, use the root=PARTUUID=<uuid> mechanism, where the
uuid is found by U-Boot.
