SubjectRe: [PATCH 2/8] dt-bindings: nvmem: sfp: Add clock properties

For some context: Sean was adding the SFP support in u-boot and
I referred him to this binding. I didn't need the clock to just
read the data. But Sean is right, we need the clock for the
programming. I was unaware of that. The binding is still yet to
be released with v5.18, thus I think it is still possible to make
the clock mandatory.
