Need to state somewhere this follows the bindings/nvmem/nvmem.txt 
binding.

Any chance I can keep it as is? I am asking because this node name is
used by the driver as device name which is how it also appears in
sysfs. Reason for that being that "main-eeprom" and "dds-eeprom"
(second EEPROM in the system) are easier to rembmer and tell apart
than "eeprom@a4" and "eeprom@a5". Granted, I can divorce naming scheme
in the driver from device node name, but then I'd have to keep a
"address -> deivce name" lookup table which I was hoping to avoid.

OK, will do in v3.

It generates a dtc warning if you don't fix it.
