[PATCH v5 1/4] dt-bindings: arm: fsl: add TQMa8MPxS board

[Alexander Stein <alexander.stein@ew.tq-group.com>]

From: Paul Gerber <paul.gerber@tq-group.com>

TQMa8MPxS is a SOM family using NXP i.MX8MP CPU family.
MB-SMARC-2 is an evaluation mainbord for this SOM

The SOM needs a mainboard, therefore we provide two compatibles here:

"tq,imx8mp-<SOM>" for the module and
"tq,imx8mp-<SOM>-<SBC>"
