Rename gpio driver file name from pinctrl-cygnus-gpio.c to
pinctrl-iproc-gpio.c to make it more generic so that all
iproc based future SoCs using the same gpio block could
use this driver.

This adds the initial support of the Broadcom Cygnus GPIO/PINCONF driver
that supports all 3 GPIO controllers on Cygnus including the ASIU GPIO
controller, the chipCommonG GPIO controller, and the always-on GPIO
controller. Basic PINCONF configurations such as bias pull up/down, and
drive strength are also supported in this driver.

Pins from the ASIU GPIO controller can be individually muxed to GPIO
function, through interaction with the Cygnus IOMUX controller

This adds the initial driver support for the Broadcom Cygnus IOMUX
controller. The Cygnus IOMUX controller supports group based mux
configuration but allows certain pins to be muxed to GPIO individually
