From: Fuyun Liang <liangfuyun1@huawei.com>
Driver gets phy address from NCL_config file and uses the phy address to initialize phydev. There are 5 bits for phy address. And C22 phy address has 5 bits. So 0-31 are all valid address for phy. If there is no phy, it will crash. Because driver always get a valid phy address.
This patch fixes the phy address to 8 bits, and use 0xff to indicate invalid phy address.
