mx6cuboxi: Use PARTUUID to specify the rootfs location 

Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the eMMC
changes depending on the kernel version.

In order to avoid such issue, use UUID method to specify the rootfs
location.

This change was made based on U-Boot commit:
