dt-bindings: net: micrel: add coma-mode-gpios property

The LAN8814 has a coma mode pin which is used to put the PHY into
isolate and power-down mode. Usually strapped to be asserted by default.
A GPIO is then used to take the PHY out of this mode.

Some PHYs have a COMA mode input pin which puts the PHY into
isolate and power-down mode. On some boards this input is connected
to a GPIO of the SoC.
