Nand: make nand support more configurable

[Sascha Hauer]

The following series makes the nand support more configurable. Currently
the nand support is quite big. Often enough a given nand controller only
needs a single ecc mode. In a xloader environment we do not need write
support and bad block tables. Support being made optional in this series
has default y to not change the existing defconfigs.

Sascha Hauer (12):
      commands: Make nand command optional
      nand: remove unused suspend/resume functions
      nand: remove unneeded nand_[get|release]_device functions
      nand: do not fall through in nand_scan_tail()
      nand: Factor out hw ecc support to seperate file
      nand: factor out software ecc support to seperate file
      nand: factor out syndrome support to seperate file
      nand: factor out nand write support
      nand: Make write support optional
      nand: Make different ecc modes optional
      nand: make vendor/type printout optional
      nand: make bbt support optional
