[PATCH v2 3/3] pinctrl: renesas: rzt2h: Add support for RZ/N2H SoC

[Prabhakar <prabhakar.csengg@gmail.com>]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

The RZ/N2H (R9A09G087) SoC from Renesas shares a similar pin controller
architecture with the RZ/T2H (R9A09G077) SoC, differing primarily in the
number of supported pins-576 on RZ/N2H versus 729 on RZ/T2H.

Add the necessary pin configuration data and compatible string to enable
support for the RZ/N2H SoC in the RZ/T2H pinctrl driver.
