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.
