Merge tag 'arm-soc/for-4.2/soc-part2' of http://github.com/broadcom/stblinux into...

Merge "changes for Broadcom SoCs":

- Dan fixes an error path in the BCM63xx SMP code

- Ray adds the relevant Kconfig selects to enable the Broadcom NAND driver on Cygnus

- Kevin provides a change to the Broadcom GISB arbiter driver to make it work with
  MIPS-based big-endian STB SoCs (this was a long-standing change that had dependencies on
  code in drivers/of/*)

- Gregory enables the use of GPIOLIB for brcmstb SoCs and bumps the number of GPIOs for
  these platforms
