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.

zcu102-revB/up are not removing phy from revA properly because of incorrect
name.

Add gpio phy reset via I2C expander TCA6416 on board ZCU102.
A warning call trace is observer in probe when this reset is called
from context that can sleep. Keep this commented until that is
resolved in phylib.

The DP83867 strap control workaround is already present in Linux kernel
mainline binding. All these Xilinx boards require this quirk.

Ethernet phys based on devicetree specification should be using
ethernet-phy@ node name instead of pure phy@.

Mainline Linux kernel has adopted SPDX header license in a different
format then was used before. This patch is syncing it up.
Also update years in License text and remove Nathalie's email because it
is no longer valid.

Some user space libraries reading platform compatible string and based
on that changing behavior. Mark revB board with revB string.

Not using board revision is causing confusion about which board is
supported and tested. Mark dts files exactly with board revision which
was tested. When new board revision arives it can be symlink if SW view
is the same. Also add -revX suffix to compatible string because user space
tools are parsing this string and can change behavior depends of board
revision.
