In which circumstances are you trying to translate an address with no
size cell ?

for the enumerated PHYs. As the original commit comment states, I was
getting these messages:

prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@00
prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@01

Specifically, which of_address_to_resource or other call is producing
these error messages?
