pinctrl: Update iProc GPIO DT bindings

Update the iProc GPIO binding document to add new compatible strings
"brcm,iproc-nsp-gpio" and "brcm,iproc-stingray-gpio" to support the
iProc based GPIO controller used in the NSP and Stingray SoCs,
respectively

Required properties:
- compatible:
Must be "brcm,cygnus-ccm-gpio", "brcm,cygnus-asiu-gpio",
"brcm,cygnus-crmu-gpio" or "brcm,iproc-gpio"
"brcm,iproc-gpio" for the generic iProc based GPIO controller IP that
supports full-featured pinctrl and GPIO functions used in various iProc
based SoCs
May contain an SoC-specific compatibility string to accommodate any
SoC-specific features
"brcm,cygnus-ccm-gpio", "brcm,cygnus-asiu-gpio", or
"brcm,cygnus-crmu-gpio" for Cygnus SoCs
"brcm,iproc-nsp-gpio" for the iProc NSP SoC that has drive strength support
disabled
"brcm,iproc-stingray-gpio" for the iProc Stingray SoC that has the general
pinctrl support completely disabled in this IP block. In Stingray, a
different IP block is used to handle pinctrl related functions
