[PATCH] dt-bindings: serial: Convert cnxt,cx92755-usart to DT schema

["Rob Herring (Arm)" <robh@kernel.org>]

Convert the Conexant Digicolor USART binding to DT schema. It is a
straight-forward conversion.

-Binding for Conexant Digicolor USART
-
-Note: this binding is only applicable for using the USART peripheral as
-UART. USART also support synchronous serial protocols like SPI and I2S. Use
-the binding that matches the wiring of your system.
-
-Required properties:
-- compatible : should be "cnxt,cx92755-usart".
-- reg: Should contain USART controller registers location and length.
-- interrupts: Should contain a single USART controller interrupt.
-- clocks: Must contain phandles to the USART clock
-  See ../clocks/clock-bindings.txt for details.
-
-Note: Each UART port should have an alias correctly numbered
-in "aliases" node.
-
-Example:
-	aliases {
-		serial0 = &uart0;
-	};
-
-	uart0: uart@f0000740 {
-		compatible = "cnxt,cx92755-usart";
-		reg = <0xf0000740 0x20>;
-		clocks = <&main_clk>;
-		interrupts = <44>;
-	};
