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.

		In fiber mode, auto-negotiation is disabled and the PHY can only work in
		100base-fx (full and half duplex) modes.

		- coma-mode-gpios: If present the given gpio will be deasserted when the
		PHY is probed.

		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.

		Supported on the LAN8814.
