dt-bindings: iio: accel: adxl345: switch to YAML bindings



The ADX345 supports both I2C & SPI bindings.
This change switches from old text bindings, to YAML bindings, and also
tries to make use of the recent multiple-examples support.

http://www.analog.com/en/products/sensors-mems/accelerometers/adxl375.html

Required properties:
 - compatible : should be one of
		"adi,adxl345"
		"adi,adxl375"
 - reg : the I2C address or SPI chip select number of the sensor

Required properties for SPI bus usage:
 - spi-max-frequency : set maximum clock frequency, must be 5000000
 - spi-cpol and spi-cpha : must be defined for adxl345 to enable SPI mode 3

Optional properties:
 - interrupts: interrupt mapping for IRQ as documented in
   Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

Example for a I2C device node:

	accelerometer@2a {
		compatible = "adi,adxl345";
		reg = <0x53>;
		interrupt-parent = <&gpio1>;
		interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
	};

Example for a SPI device node:

	accelerometer@0 {
		compatible = "adi,adxl345";
		reg = <0>;
		spi-max-frequency = <5000000>;
		spi-cpol;
		spi-cpha;
		interrupt-parent = <&gpio1>;
		interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
	};
