dt-bindings:iio:dac:nxp,lpc1850-dac yaml conversion.

Very similar binding to that for the ADC on the same device.
Conversion from txt to yaml format.

-NXP LPC1850 DAC bindings

-Required properties:
-- compatible: Should be "nxp,lpc1850-dac"
-- reg: Offset and length of the register set for the ADC device
-- interrupts: The interrupt number for the ADC device
-- clocks: The root clock of the ADC controller
-- vref-supply: The regulator supply ADC reference voltage
-- resets: phandle to reset controller and line specifier
-
-Example:
-dac: dac@400e1000 {
-	compatible = "nxp,lpc1850-dac";
-	reg = <0x400e1000 0x1000>;
-	interrupts = <0>;
-	clocks = <&ccu1 CLK_APB3_DAC>;
-	vref-supply = <&reg_vdda>;
-	resets = <&rgu 42>;
-};
