bmp085.yaml: transform DT documentation of iio sensor into YAML

BMP085/BMP18x/BMP28x digital pressure sensors

Required properties:

- compatible: must be one of:

  "bosch,bmp085"

  "bosch,bmp180"

  "bosch,bmp280"

  "bosch,bme280"

Optional properties:

- interrupts: interrupt mapping for IRQ

- reset-gpios: a GPIO line handling reset of the sensor: as the line is

  active low, it should be marked GPIO_ACTIVE_LOW (see gpio/gpio.txt)

- vddd-supply: digital voltage regulator (see regulator/regulator.txt)

- vdda-supply: analog voltage regulator (see regulator/regulator.txt)

Example:

pressure@77 {

	compatible = "bosch,bmp085";

	reg = <0x77>;

	interrupt-parent = <&gpio0>;

	interrupts = <25 IRQ_TYPE_EDGE_RISING>;

	reset-gpios = <&gpio0 26 GPIO_ACTIVE_LOW>;

	vddd-supply = <&foo>;

	vdda-supply = <&bar>;
