[PATCH v3 2/3] arm64: dts: imx93: add Engicam i.Core MX93 SoM

From: Fabio Aiuto
Date: Fri Apr 19 2024 - 10:53:25 EST

i.Core MX93 is a NXP i.MX93 based EDIMM SoM
by Engicam.

Main features:

CPU: NXP i.MX 93
MEMORY: Up to 2GB LPDDR4
NETWORKING: 2x Gb Ethernet
USB: USB OTG 2.0, USB HOST 2.0
STORAGE: eMMC starting from 4GB
PERIPHERALS: UART, I2C, SPI, CAN, SDIO, GPIO

The i.Core MX93 needs to be mounted on top of
Engicam baseboards to work.

Add devicetree include file.
