nand patches

[Sascha Hauer]

Some more nand cleanup. The badblock device code is moved from
the nand command to drivers/mtd to make it work without the command.

Sascha Hauer (4):
      nand: nand_block_markbad is only used with nand write support
      nand: move bb handling code to drivers/mtd/nand
      nand bb: switch to cdev operations
      nand bb: add proper bb remove function
