[NAND] Bad block skipping for command nboot

Browse source 
The old implementation of command nboot does not support reading the image from
NAND flash with skipping of bad blocks. The patch implements a new version of
the nboot command: by calling nboot.jffs2 from the u-boot command line the
command will load the image from NAND flash with respect to bad blocks (by using
nand_read_opts()). This is similar to e.g. the NAND read command: "nand
read.jffs2 ...".
