arm64: zynqmp: Describe TI phy as ethernet-phy-id

TI DP83867 is using strapping based on MIO pins. Tristate setup can influce
PHY address. That's why switch description with ethernet-phy-id compatible
string which enable calling reset. PHY itself setups phy address after
power up or reset. Reset description will be added in separate commit.
