arm64: zynqmp: Describe TI phy as ethernet phy ID on ZCU102 RevB & up
TI phy requires a reset before PHY address detection to make sure
correct strapping via MIO is detected. Facilitate the same using
ethernet-phy-id compatible string. GPIO reset entry will be added in
a separate commit.
This support is present in RevA but needs to be extended to RevB/1.0/1.1
versions which are built on top.
