[lisa_m] baro: resurrect the bmp085 driver that Michal removed
This is again the default with Lisa/M, three baro drivers to choose:
- BARO_BOARD_BMP085 (default)
- BARO_MS5611_SPI
- BARO_MS5611_I2C
To use the MS5611 on the Aspirin IMU, configure it in your firmware section, e.g.:
<configure name="LISA_M_BARO" value="BARO_MS5611_SPI"/>
