Hmm, bindings/nvmem/zii,rave-sp-eeprom.txt suggests there could be child
nodes?

"Data cells are child nodes of eerpom node, bindings for which are
documented in Documentation/devicetree/bindings/nvmem/nvmem.txt"

It should be optional property to declear offset, such as mac_address, or
watchdog_timeout value.

Here is no children nodes under eeprom@a4, so needn't #address-cells. It
should be added only when add children nodes.
