pinctrl: pinctrl-microchip-sgpio: Add pinctrl driver for Microsemi Serial GPIO
This adds a pinctrl driver for the Microsemi/Microchip Serial GPIO (SGPIO) device used in various SoC's. The driver is added as a pinctrl driver, albeit only having just GPIO support currently. The hardware supports other functions that will be added following.

+ Support for the serial GPIO interface used on Microsemi and
+ Microchip SoC's. By using a serial interface, the SIO
+ controller significantly extends the number of available
+ GPIOs with a minimum number of additional pins on the
+ device. The primary purpose of the SIO controller is to
+ connect control signals from SFP modules and to act as an
+ LED controller.
