LIS3MDL and LSM9DS1 are missing BDU settings in their register maps, so add
them. I don't have a LIS3MDL sensor to test, but this works correctly on
the LSM9DS1, which has the same register map.

Update the sensor settings to support the LSM9DS1 sensor. Although the
LSM9DS1 accelerometer and gyroscope are coupled together to use the same
FIFO, the magnetometer is separate and can be cleanly supported without
refactoring the existing driver.

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
Notice that in this particular case, I replaced "...and fall through."
with the specific string "fall through", which is what GCC is
expecting to find thus supressing this false positive.
As Peter has observed this breaks the nice English flow, which is
less than ideal, but short of teaching GCC to read English, there
isn't a lot that we can do about it.

The charme of devm_* functions is that you don't need to care about them
