i.Core MX93 is a NXP i.MX93 based SoM by Enigcam which needs to be
mounted on top of Engicam baseboards.

Add support for EDIMM 2.0 Starter Kit hosting i.Core MX93.

Starter Kit main features:

2x LVDS interfaces
HDMI output
Audio out
Mic in
Micro SD card slot
USB 3.0 A port
3x USB 2.0 A port
Gb Ethernet
2x CAN bus, 3x UART interfaces
SIM card slot
M.2 KEY_B slot
