Synopsys DWAPB IP includes support for pin control. This control is basic
and allows to switch between a hardware and a software function.
Software function is when driving GPIOs from IP and hardware is controlled
by external signals.
This serie export necessary interface to be able to move the driver to
pinctrl folder and then implement the pinctrl support which is based on the
digicolor driver. The idea is to avoid hardcoding pins in driver since
this IP is a generic one available on multiple SoC.

gpio: export acpi_gpiochip_request_interrupts in gpio/driver.h
pinctrl: dw: move gpio-dwapb.c to pinctrl folder
pinctrl: dw: use devm_gpiochip_add_data
pinctrl: dw: add pinctrl support for dwapb gpio driver
dt-bindings: pinctrl: dw: move sps,dwapb-gpio.txt to pinctrl
