arm64: dts: S32G3: Introduce device tree for S32G-VNP-RDB3

Browse source 
This commit adds device tree support for the NXP S32G3-based
S32G-VNP-RDB3 Board [1].

The S32G3 features an 8-core ARM Cortex-A53 based SoC developed by NXP.

The device tree files are derived from the official NXP downstream
Linux tree [2].

This addition encompasses a limited selection of peripherals that
are upstream-supported. Apart from the ARM System Modules
(GIC, Generic Timer, etc.), the following IPs have been validated:

    * UART: fsl-linflexuart
    * SDHC: fsl-imx-esdhc

Clock settings for the chip rely on ATF Firmware [3].
Pin control integration into the device tree is pending and currently
relies on Firmware/U-Boot settings [4].

These changes were validated using BSP39 Firmware/U-Boot from NXP [5].

The modifications enable booting the official Ubuntu 22.04 from NXP on
the RDB3 with default settings from the SD card and eMMC.
