[PATCH] dt-bindings: net: convert microchip,lan78xx.txt to YAML schema

[Mikhail Lukianchikov <avermoal@gmail.com>]

Convert the Microchip LAN78xx family (LAN7800, LAN7801, LAN7850) binding
documentation from plain text to DT schema format using YAML.

The conversion was validated with 'make dt_binding_check'

-Microchip LAN78xx Gigabit Ethernet controller
-
-The LAN78XX devices are usually configured by programming their OTP or with
-an external EEPROM, but some platforms (e.g. Raspberry Pi 3 B+) have neither.
-The Device Tree properties, if present, override the OTP and EEPROM.
-
-Required properties:
-- compatible: Should be one of "usb424,7800", "usb424,7801" or "usb424,7850".
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt.
-
-Optional properties of the embedded PHY:
-- microchip,led-modes: a 0..4 element vector, with each element configuring
-  the operating mode of an LED. Omitted LEDs are turned off. Allowed values
-  are defined in "include/dt-bindings/net/microchip-lan78xx.h".
-
-Example:
-
-/* Based on the configuration for a Raspberry Pi 3 B+ */
-&usb {
-	usb-port@1 {
-		compatible = "usb424,2514";
-		reg = <1>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		usb-port@1 {
-			compatible = "usb424,2514";
-			reg = <1>;
-			#address-cells = <1>;
-			#size-cells = <0>;
-
-			ethernet: ethernet@1 {
-				compatible = "usb424,7800";
-				reg = <1>;
-				local-mac-address = [ 00 11 22 33 44 55 ];
-
-				mdio {
-					#address-cells = <0x1>;
-					#size-cells = <0x0>;
-					eth_phy: ethernet-phy@1 {
-						reg = <1>;
-						microchip,led-modes = <
-							LAN78XX_LINK_1000_ACTIVITY
-							LAN78XX_LINK_10_100_ACTIVITY
