sdp3x: remove reset during init

Browse Source 
It is not playing nice with other devices on the same bus.
In particular with the FreeFly RTK GPS: once the reset is sent, the whole
bus is blocked and becomes unusable.
Current understanding is that this device contains another chip on the bus
(apart from the mag+baro+led).

I don't see much use for it either, as we configure everything there is to
configure (just the mode).
