dt-bindings: iio: adc: microchip,mcp3201 yaml conversion.

Drops the deprecated compatibles without the vendor name.
Whilst the driver continues to support these for old dt blobs,
any dt bindings that are actuallly verified against this document should
be fixed to add the vendor name.

Added the #io-channel-cells property to allow for consumers.

-The node for this driver must be a child node of a SPI controller, hence

-
-        Documentation/devicetree/bindings/spi/spi-bus.txt

-must be specified.
-
-Required properties:
-	- compatible:  	Must be one of the following, depending on the
-			model:
-				"mcp3001" (DEPRECATED)
-				"mcp3002" (DEPRECATED)
-				"mcp3004" (DEPRECATED)

-
-			NOTE: The use of the compatibles with no vendor prefix
-			is deprecated and only listed because old DT use them.
-
-	- spi-cpha, spi-cpol (boolean):
-			Either SPI mode (0,0) or (1,1) must be used, so specify
-			none or both of spi-cpha, spi-cpol.  The MCP3550/1/3
-			is more efficient in mode (1,1) as only 3 instead of
-			4 bytes need to be read from the ADC, but not all SPI
-			masters support it.
-
-	- vref-supply:	Phandle to the external reference voltage supply.

-Examples:
-spi_controller {
-	mcp3x0x@0 {
-		compatible = "microchip,mcp3002";
-		reg = <0>;
-		spi-max-frequency = <1000000>;
-		vref-supply = <&vref_reg>;
