Subject: [PATCH v2 1/2] dt-bindings: net: adin: add recovered clock output

The ADIN1300 offers three distinct output clocks which can be accessed
through the GP_CLK pin. The DT only offers two of the possible options
and thus the 125MHz-recovered output clock is missing.

As there is no other way to configure this pin than through the DT it
should be possible to do so for all available outputs.
