_register_write instead.

AP_InertialSensor: always sample at 200Hz in MPU6000
...
this changes the sampling to 200Hz regardless of requested rate, and
it is downsampled inside num_samples_available() using a shift. This
gives better noise resistance in ArduPlane.
This patch also makes it possible to update the filter frequency while
running, which is very useful for bench testing with a vibration
source

rate
