cns3xxx: eliminate hardcoded kernel/rootfs partition split
This changes the sysupgrade format. To support upgrades from the old firmware to the new one, legacy images are provided. Because of the old partition split, these have to be specific to the NOR or SPI device. The new sysupgrade images are suitable for begin put on flash directly, and they are independent of NOR vs SPI flash variant. Flashing back to old firmware is supported via using the old full-flash images instead of the old sysupgrade images. Signed-off-by: Felix Fietkau <nbd@nbd.name>
