Baro MS5611 driver for I2C, SPI and auxI2C bus on Lisa M 2.0/Lia 1.1
* I2C - works with Aspirin 2.1, we have to define MPU6000_NO_SLAVES
* SPI - works with Aspirin 2.2
* generic - reading of barometers is done through Aspirin aux I2C (for Aspirin 2.1)

rotorcraft.makefile - here we choose which bus to use, if you have a better idea how to decide let me know

aspirin makefile - had to add a check for duplicities in ap.srcs and ap.CFLAGS, otherwise there was multiple definition of spi interfaces

main.c - default baro frequency is 100, which corresponds to roughly 20 baro updates per second, which is maximal possible value for
highest precision pressure calculation on MS5611

Fixed telemetry - returned to default values
MS5611 definitions moved to peripherials, added Aspirin 2.2. makefile, taken care of slave selection for Aspirin 2.1
main BARO_PERIODIC_FREQUENCY returned to default value (roughly 10Hz for MS5611)
Airframe and lisa makefile back to default values
Fixed debug messages
Merge pull request #341 from podhrmic/master
