Ah damn, this looks like a consistency problem is coming up. We have
multiple PCM* SoMs in U-Boot, one PCL* SoM and now another PCL/PCM SoM.
But the PCL063 isn't even manufactured in variant with connectors, so I
guess we can ignore that one.

I wonder whether we should stick to PCM* for all of the Phytec SoMs for
consistency sake and document that PCL060 is also supported or maybe
there's a better way ?
