The commit 6c993815bbea ("net: phy: xilinx: Be compatible with live OF tree") change driver behavior to while loop which wasn't correct because the driver was looping over again and again. The reason was that ofnode_valid() is taking 0 as correct value. Fix it by changing while loop to ofnode_for_each_subnode() which is only loop over available nodes.
