E.g. instead of defining a gyro_scale struct in drv_gyro.h, use the
gyro_calibration message.

Trailing whitespace all over.

This adds uORB messages to publish calibration data by sensors which is
then consumed by the sensors. Currently this is only used on Snapdragon
and guarded by QURT ifdefs.

This reverts commit 213cdf1a.

Raising the stream rate of param values had the nice effect that
receiving the params became really quick. However, on the downside it
set all other streams pretty slow. This needs to be fixed differently.

This was in there by accident.

There is no calibration config needed anymore.

The calibration config is no longer needed.

The recent workaround to flag all params as used did not include
param_for_used_index(). However, this function got used in the case if
one param had not been received by QGC and was requested by its index.

Revert "px4flow: disable distance data transmission from px4flow sensor"

This reverts commit 47f79a66 because it
was just an intermediate debug commit.

Previously we only published pressure which wasn't inav for the position
estimator.
