- compatible: bosch,bmp085

"bosch,bmp085"
"bosch,bmp180"
"bosch,bmp280"
"bosch,bme280"
Optional properties:
- chip-id: configurable chip id for non-default chip revisions

value range is 0-3 with rising sensitivity.
- interrupt-parent: should be the phandle for the interrupt controller
- 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)
