The problem is real but I think the fix belongs in network-class.yaml rather
than the brcmfmac binding specifically. ethernet-controller.yaml already
defines nvmem-cells and nvmem-cell-names for wired NICs, but the wireless
binding hierarchy (wireless-controller.yaml -> network-class.yaml) is missing
them. Fixing it in network-class.yaml would cover all network nodes at once
instead of requiring each wireless driver to add the same reference
individually.
