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.
