[PATCH 4/5] arm64: dts: freescale: support Engicam i.Core MX8M Plus FE C.TOUCH 2.0 board

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

Support Engicam i.Core MX8M Plus Fast Ethernet C.TOUCH 2.0 board with:

 - 10/100 Ethernet
 - CAN
 - RTC
 - USB host, through an on-board hub
 - USB OTG, device only
 - Micro SD card connector
 - LVDS display connector

The C.TOUCH 2.0 carrier board is described in a separate dtsi, so that
it can be shared with the other i.Core MX8M Plus SoMs.
