ARM: i.MX: Add bbu handler for external NAND boot
The external NAND boot code currently does not handle bad blocks
correctly on 2k NAND flashes. This patch adds a barebox_update
handler for external NAND boot which embeds a Bad block table in
the flashed image. The boot code will skip bad blocks found in
this bad block table then.
