Oops, I've been (manually) re-adding and removing it again too many
times during my investigations. "#nvmem-cell-cells", of course.
According to my build logs, I had it right at least once ;-)

Anyway, with or without the typo, the error message is about the same:

- Unevaluated properties are not allowed ('nvmem-cell-cells' was unexpected)
+ Unevaluated properties are not allowed ('#nvmem-cell-cells' was unexpected)
