i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini
from Engicam.
General features:
- NXP i.MX8M Mini
- Up to 2GB LDDR4
- 8/16GB eMMC
- Gigabit Ethernet
- USB 2.0 Host/OTG
- PCIe Gen2 interface
- I2S
- MIPI DSI to LVDS
- rest of i.MX8M Mini features
i.Core MX8M Mini needs to mount on top of Engicam baseboards
for creating complete platform solutions.
Add support for it.

Changes for v3:
- keep regulator min/max hoping
Changes for v2:
- updated commit message
- add cpu nodes
- add fec1 node
- fixed pmic tree comments
- dropped engicam from filename since it aligned with imx6 engicam
dts files naming conventions.
