rb532: really fix squashfs 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.
