[POWERPC] Don't complain if size-cells == 0 in prom_parse()
An mdio bus scan was added with ucc_geth phylib migration patches, now machines complain on boot, saying: 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 since size-cells can indeed be 0, this patch fixes the check.
