Two series lived in parallel for some time, which led to this situation:
- The nvmem-layout container is used for dynamic layouts
- We now expect fixed layouts to also use the nvmem-layout container but
this does not require any additional driver, the support is built-in the
nvmem core.
Ensure we don't refuse to probe for wrong reasons.

Please note this is a temporary fix as this piece of code is going to
disappear when the NVMEM layouts 'as devices' series gets in.
