Subject: [PATCH RESEND 2/9] dt-bindings: pinctrl: renesas: Document RZ/G3L SoC

From: Biju Das <biju.das.jz@...renesas.com>

Add documentation for the pin controller found on the Renesas RZ/G3L
(R9A08G046) SoC. The RZ/G3L PFC is similar to the RZ/G3S SoC but has
more pins.

Also add header file similar to RZ/G3E and RZ/V2H as it has alpha
numeric ports.
