    sunxi: make sdcard image with squashfs as rootfs
    
    Two things that need to be noted
    
     - There is no partition type id allocated for squashfs yet.  In the
       case of sunxi, any non-zero value should work and we keep it 83 (the
       value for ext4)
     - Remaining spare space within the rootfs partition, not the entire
       sdcard space will be formated as either f2fs or ext4 and mounted as
       overlay to serve the role of rootfs_data.
