I'm not sure what you exactly mean. The warning isn't about using fsl,imx8mm-mipi-dsim, instead
fsl,imx7d-mipi-dsim does not match any compatibles listed in the schema.

Admittedly I'm having a hard time on DT schemas at times, but this change allows
imx7d OR imx8mn to be used together with imx8mm.

This patch essentially does the same but add a new entry to the oneOf.
If you add fsl,imx8mn-mipi-dsim to that enum as we end up with the same
solution.
