Mugunthan V N 9c653aad16 drivers: net: cpsw: add support to have phy address from cpsw platform data
Some platforms like AM437x have different EVMs with different phy addresses,
so this patch adds support for passing phy address via cpsw plaform data.
Also renamed phy_id to phy_addr so better understanding of the code.
