BMP085/BMP18x digital pressure sensors

Required properties:
- compatible: bosch,bmp085

Optional properties:
- chip-id: configurable chip id for non-default chip revisions
- temp-measurement-period: temperature measurement period (milliseconds)
- default-oversampling: default oversampling value to be used at startup,
  value range is 0-3 with rising sensitivity.
- interrupt-parent: should be the phandle for the interrupt controller
- interrupts: interrupt mapping for IRQ

Example:

pressure@77 {
	compatible = "bosch,bmp085";
	reg = <0x77>;
	chip-id = <10>;
	temp-measurement-period = <100>;
	default-oversampling = <2>;
	interrupt-parent = <&gpio0>;
	interrupts = <25 IRQ_TYPE_EDGE_RISING>;
};
