dfu, nand: before write a buffer to nand, erase the nand sectors
before writing the received buffer to nand, erase the nand
sectors. If not doing this, nand write fails. See for
more info here:
http://lists.denx.de/pipermail/u-boot/2013-June/156361.html
Using the nand erase option "spread", maybe overwrite
blocks on, for example another mtd partition, if the
erasing range contains bad blocks.
So a limit option is added to nand_erase_opts()
