In new SigmaStar SoCs they have moved away from having a few
interrupt capable GPIOs and instead have chained yet another
interrupt controller in to provide interrupt support for
all of the GPIOs.
I'm hardly an IRQ expert so I expect I've made a total
mess of this. No one else was going to write this driver
so I had a go.

dt-bindings: interrupt-controller: Add SigmaStar SSD20xD gpi
irqchip: SigmaStar SSD20xD gpi
ARM: dts: mstar: Add gpi interrupt controller to i2m
