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 at 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 at 0 {
- reg = <1>;
- };
- };
