NAND: Make nboot skip bad blocks

Browse Source 
nboot command currently does not skip bad blocks and gives read error when
loading image stored over bad block. With patch applied, nboot works as
expected:

Device 0 bad blocks:
  00780000
  014a0000
  02000000
  02cc0000
  04aa0000

Loading from NAND 128MiB 3,3V 8-bit, offset 0x2c00000
   Image Name:   Linux-2.6.22-omap1
