Add support to the iProc GPIO driver for v2 and v3 revisions of the iProc GPIO
controllers. The v2 revision is used on NSP with drive strength pinconf
feature disabled and the v3 revision is used on Stingray with all pinconf
features disabled

Changes from v1:
 - Changed to use compatible strings "brcm,iproc-gpio-v2" and
"brcm,iproc-gpio-v3" to deal with differences among various iProc based SoCs
 - Removed DT header "include/dt-bindings/pinctrl/brcm,iproc-gpio.h"

Patch series is developed based on Linux v4.6-rc1 and available at:
https://github.com/Broadcom/cygnus-linux/tree/iproc-gpio-v2
