dt-bindings: net: remove arc_emac.txt 



The last real user nSIM_700 of the "snps,arc-emac" compatible string in
a driver was removed in 2019. The use of this string in the combined DT of
rk3066a/rk3188 as place holder has also been replaced, so
remove arc_emac.txt

* Synopsys ARC EMAC 10/100 Ethernet driver (EMAC)



Required properties:

- compatible: Should be "snps,arc-emac"

- reg: Address and length of the register set for the device

- interrupts: Should contain the EMAC interrupts

- max-speed: see ethernet.txt file in the same directory.

- phy: see ethernet.txt file in the same directory.



Optional properties:

- phy-reset-gpios : Should specify the gpio for phy reset

- phy-reset-duration : Reset duration in milliseconds.  Should present

  only if property "phy-reset-gpios" is available.  Missing the property

  will have the duration be 1 millisecond.  Numbers greater than 1000 are

  invalid and 1 millisecond will be used instead.



Clock handling:

The clock frequency is needed to calculate and set polling period of EMAC.

It must be provided by one of:

- clock-frequency: CPU frequency.

- clocks: reference to the clock supplying the EMAC.



Child nodes of the driver are the individual PHY devices connected to the

MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.



Examples:



	ethernet@c0fc2000 {

		compatible = "snps,arc-emac";

		reg = <0xc0fc2000 0x3c>;

		interrupts = <6>;

		mac-address = [ 00 11 22 33 44 55 ];



		clock-frequency = <80000000>;

		/* or */

		clocks = <&emac_clock>;



		max-speed = <100>;

		phy = <&phy0>;



		#address-cells = <1>;

		#size-cells = <0>;

		phy0: ethernet-phy@0 {

			reg = <1>;

		};

	};
