nxp,lpc1850-uart.txt binding is already covered by 8250.yaml, so remove
it.

* NXP LPC1850 UART



Required properties:

- compatible	: "nxp,lpc1850-uart", "ns16550a".

- reg		: offset and length of the register set for the device.

- interrupts	: should contain uart interrupt.

- clocks	: phandle to the input clocks.

- clock-names	: required elements: "uartclk", "reg".



Optional properties:

- dmas		: Two or more DMA channel specifiers following the

		  convention outlined in bindings/dma/dma.txt

- dma-names	: Names for the dma channels, if present. There must

		  be at least one channel named "tx" for transmit

		  and named "rx" for receive.



Since it's also possible to also use the of_serial.c driver all

parameters from 8250.txt also apply but are optional.



Example:

uart0: serial@40081000 {

	compatible = "nxp,lpc1850-uart", "ns16550a";

	reg = <0x40081000 0x1000>;

	reg-shift = <2>;

	interrupts = <24>;

	clocks = <&ccu2 CLK_APB0_UART0>, <&ccu1 CLK_CPU_UART0>;

	clock-names = "uartclk", "reg";

};
