Michael Walle 4fdabd509d dt-bindings: net: lan966x: remove PHY reset
The PHY reset was intended to be a phandle for a special PHY reset
driver for the integrated PHYs as well as any external PHYs. It turns
out, that the culprit is how the reset of the switch device is done.
In particular, the switch reset also affects other subsystems like
the GPIO and the SGPIO block and it happens to be the case that the
reset lines of the external PHYs are connected to a common GPIO line.
Thus as soon as the switch issues a reset during probe time, all the
external PHYs will go into reset because all the GPIO lines will
switch to input and the pull-down on that signal will take effect.

So even if there was a special PHY reset driver, it (1) won't fix
the root cause of the problem and (2) it won't fix all the other
consumers of GPIO lines which will also be reset.

It turns out, the Ocelot SoC has the same weird behavior (or the
lack of a dedicated switch reset) and there the problem is already
solved and all the bits and pieces are already there and this PHY
reset property isn't not needed at all.

There are no users of this binding. Just remove it.
