[PATCH v2 1/4] dt-bindings: pinctrl: renesas: Document RZ/G3E SoC

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

Add documentation for the pin controller found on the Renesas RZ/G3E
(R9A09G047) SoC. The RZ/G3E PFC is similar to the RZ/V2H SoC but has more
pins(P00-PS3). The port number is alpha-numeric compared to the number on
the other SoCs. So add macros for alpha-numeric to number conversion.
