This is ported this from Broadcom's XLDK (now heavily modified). There seem to
be 3 different IP blocks for 3 separate banks of GPIOs in the iProc chips.
I've dropped everything except support for the Chip Common A GPIO
controller because the other blocks actually seem to be supportable with
other drivers. The driver itself is halfway between pinctrl-nsp-gpio.c
and pinctrl-iproc-gpio.c.
