I stumbled on that sentence when making the changes and it definitely
does not apply to the BMA* variants. Those are accelerometer only.

As far I can tell the prefix in the chip name says which kind of sensors
are included, i.e.

  - BMC150: accelerometer + magnetometer
  - BMA*:   only accelerometer

I'm not familiar with BMI055 but funnily the datasheet suggests it's

  - BMI055: accelerometer + gyroscope

So for BMI055 the previous message is wrong too. I guess I need to do
yet another commit in v3 to make the Kconfig option more clear for all
the sensor variants. :)

Thanks!
