dt-bindings: Add 1027/1029/1031 SPI ADCs as trivial devices 



In the same time, remove the dedicated bindings file which is now
useless.

* Maxim 1027/1029/1031 Analog to Digital Converter (ADC)



Required properties:

  - compatible: Should be "maxim,max1027" or "maxim,max1029" or "maxim,max1031"

  - reg: SPI chip select number for the device



Optional properties:

  - interrupts: IRQ line for the ADC

  see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt



Recommended properties:

- spi-max-frequency: Definition as per

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



Example:

adc@0 {

	compatible = "maxim,max1027";

	reg = <0>;

	interrupt-parent = <&gpio5>;

	interrupts = <15 IRQ_TYPE_EDGE_RISING>;

	spi-max-frequency = <1000000>;

};
