[PATCH v4 03/11] mtd: brcmnand: add support for STB chips

[Brian Norris <computersforpeace@gmail.com>]

BCM7xxx chips are supported entirely by the library code, since they use
generic irqchip interfaces and don't need any extra SoC-specific
configuration.

v4: pulled stub platform driver into its own file as part of the
    library-ization. This is also important, to keep the STB driver from
    overriding the iproc_nand driver, when seeing a compatible property like:

      compatible = "brcm,nand-iproc", "brcm,brcmnand-v6.1", "brcm,brcmnand";
