Add the "realtek,rlt9300-gpio", "realtek,otto-gpio" compatible for GPIO nodes on the RTL930x SoC series. This SoC requires an extra register range, defining the interrupt CPU mapping registers.

2021-05-05dt-bindings: gpio: Binding for Realtek Otto GPIOSander Vanheule
Add a binding description for Realtek's GPIO controller found on several of their MIPS-based SoCs (codenamed Otto), such as the RTL838x and RTL839x series of switch SoCs. A fallback binding 'realtek,otto-gpio' is provided for cases where the actual port ordering is not known yet, and enabling the interrupt controller may result in uncaught interrupts.
