arm64: dts: freescale: Add support for the GOcontroll Moduline Display

Merge series from Maud Spierings <maudspierings@gocontroll.com>:

Add inital support for 2 variants of the Moduline Display controller
module slot.  This system is powered by the Ka-Ro Electronics tx8p-ml81
COM, which features an imx8mp SoC.

description:
  The GOcontroll Moduline module slot represents a connector that fullfills the
  Moduline slot specification, and can thus house any IO module that is also
  built to this spec.
