dt-bindings: adxl372: Document the adxl372 I2C bindings 

The adxl372 is designed to communicate in either SPI or I2C protocol.
This patch adds the documentation of device tree bindings for adxl372
I2C.

Required properties:
- compatible : should be "adi,adxl372"
- reg: SPI chip select number for the device
- reg: the I2C address or SPI chip select number for the device
Required properties for SPI bus usage:
- spi-max-frequency: Max SPI frequency to use
Optional properties:
- interrupts: interrupt mapping for IRQ as documented in
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
Example:
Example for a I2C device node:
accelerometer@53 {
compatible = "adi,adxl372";
reg = <0x53>;
interrupt-parent = <&gpio>;
interrupts = <25 IRQ_TYPE_EDGE_FALLING>;
};
Example for a SPI device node:
accelerometer@0 {
compatible = "adi,adxl372";
