i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini from Engicam.
i.Core MX8M Mini needs to mount on top of this Evaluation board for
creating complete i.Core MX8M Mini EDIMM2.2 Starter Kit.
PCIe, DSI, CSI nodes will add it into imx8mm-engicam-edimm2.2.dtsi once
Mainline Linux supported.
Add support for it.

Changes for v4:
- don't create carrier board dtsi, move changes in final dts.
Changes for v3:
- don't maintain common nodes and include it, if no feature diff
Changes for v2:
- enabled fec1 node
- updated commit message
- dropped engicam from filename since it aligned with imx6 engicam
dts files naming conventions.
- add i2c nodes
- fixed v1 comments
