lantiq: use BT HomeHub 5 Type A OEM partition layout
This way the on nand bad block table is preserved and used. Add support for nand OOB ECC checksums as well. It should fix all reported ubi errors, which were all related to bad nand blocks and a purged on nand bad block table. The existing ubi partition will be reused, which eliminates the need to touch the caldata during initial install. The BT u-boot has support for loading a kernel from an ubi volume. It isn't necessary any longer to replace the BT u-boot with a custom compiled one to use LEDE. It is required to restore the BT Firmware and install LEDE from scratch to switch to the new partition layout. An image for restoring the BT firmware and installing LEDE is provided at https://github.com/mkresin/lede/releases. Signed-off-by: Mathias Kresin <dev@kresin.me>owl
