base-files: sysupgrade-tar: allow separated kernel/rootfs ubi
There are some devices putting kernel and rootfs on separated ubi volumes. To make OpenWrt compatible with their bootloader, we need to put kernel and rootfs into separated ubi volumes. Add support for CI_KERN_UBIPART and CI_ROOT_UBIPART for this situation. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
