Subject: dt-bindings:iio:adc:fsl,imx7d-adc yaml conversion

A nice simple binding.  Only real different from txt is that I dropped
some descriptions where the naming of the parameter was self explanatory

-Freescale imx7d ADC bindings
-
-The devicetree bindings are for the ADC driver written for
-imx7d SoC.
-
-Required properties:
-- compatible: Should be "fsl,imx7d-adc"
-- 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
-- clock-names: Must contain "adc", matching entry in the clocks property
-- vref-supply: The regulator supply ADC reference voltage
-- #io-channel-cells: Must be 1 as per ../iio-bindings.txt
-
-Example:
-adc1: adc@30610000 {
-	compatible = "fsl,imx7d-adc";
-	reg = <0x30610000 0x10000>;
-	interrupts = <GIC_SPI 98 IRQ_TYPE_LEVEL_HIGH>;
-	clocks = <&clks IMX7D_ADC_ROOT_CLK>;
-	clock-names = "adc";
-	vref-supply = <&reg_vcc_3v3_mcu>;
-	#io-channel-cells = <1>;
-};
