fix bmi055: increase DLPF from 62.5 to 500

Browse Source 
With a DLPF of 62.5 Hz, the sampling rate is apperently not 1 kHz anymore,
because the driver got duplicate samples and published only at 128 Hz.
We have to increase the filter back to 500 Hz so that we get 1 kHz sampling
rate, with 250 Hz publications.
