The existing binding doesn't cover these boards then and needs to be
extended, no? How about following patch?

[I guess we need to keep the two-compatible list they were originally
 in for compatibility even if it's unused among upstream device trees?]

Subject: [RFC PATCH] dt-bindings: arm: fsl: add technexion,imx6dl-pico compatible

The technexion,imx6dl-pico -dwarf, -hobbit, -nymph and -pi all use the
same SoM. Reflect this compatibility with the SoM in the binding.
