net: phy: xilinx: Be compatible with live OF tree
Following the same updates that were done to the fixed phy driver, use ofnode_ APIs instead of fdt_ APIs so that the Xilinx PHY driver can support live DT. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
