dt-bindings: pinctrl: renesas: Document RZ/T2H and RZ/N2H SoCs
Document the pin and GPIO controller IP for the Renesas RZ/T2H
(R9A09G077) and RZ/N2H (R9A09G087) SoCs, and add the shared DTSI header
file used by both the bindings and the driver.
The RZ/T2H SoC supports 729 pins, while RZ/N2H supports 576 pins.
Both share the same controller architecture; separate compatible strings
are added for each SoC to distinguish them.
