This adds 'interrupt-controller' features for the signals available on
the Microchip SGPIO controller, however only for controller versions
on the Sparx5 platform (or later).

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.
