[PATCH 2/5] dt-bindings: arm: fsl: support Engicam i.Core MX8M Plus FE C.TOUCH 2.0 board

[Dario Binacchi <dario.binacchi@amarulasolutions.com>]

Add devicetree bindings for Engicam i.Core MX8M Plus Fast Ethernet
C.TOUCH 2.0 board based on the Engicam i.Core MX8M Plus Fast Ethernet
SoM (System-on-Module).

Unlike the i.Core MX8M Plus SoM, the Fast Ethernet variant embeds an
RMII 10/100 Ethernet PHY, so a dedicated SoM compatible is added.

The use of an enum for a single element is justified by the future
addition of other boards based on the same SoM.
