    [rb532] really fix squashfx images
    
    The previous attempt (r40717) to fix squashfx made the system bootable but overlayfs remained broken.
    This enables block2mtd again using the right partition number and naming and adds MTD_ROOTFS_SPLIT option.
    However onboard rootfs partition name had to be renamed to place overlay on CF instead of onboard NAND.
