mtd: add support for bad blocks in NAND flash

NAND flash is very likely to contain bad blocks.

Currently, mtd and therefore sysupgrade fails when it encounters a single bad block, potentially leaving an unbootable system.

This patch allows the mtd utility to skip bad blocks in NAND flash and complete sysupgrade successfully.
