[PATCH net-next v3 2/4] dt-bindings: net: adi,ad3306: add reset-gpios property

[Alessandro Zini]

The ADIN1140/AD3306 MAC-PHY has an active-low hardware reset pin, and the
driver binds to the common OA TC6 library which is gaining support for an
optional reset GPIO. As the schema uses "unevaluatedProperties: false", a
board description using the property would otherwise be rejected.

Add the optional reset-gpios property to describe the connection to that
pin.

Changes in v3:
- New patch, so that a board using reset-gpios with the adi,adin1140 /
  adi,ad3306 compatibles is not rejected by dt_binding_check.
