dragon: sensor: Increase accel/gyro max sensor frequency.

Since we cap the interrupt frequency, we can drive sensor frequency
higher, as long as they are not in forced mode.
Compass was already at maximum frequency.

BUG=b:25425420
TEST=pass cts test in loop (SingleSensorTests and BatchSensorTest)
