In particular:
- Enable regulators *after* configuring the voltage
- Allow 1 ms for the voltages to settle
- Enable clock after powering on regulators
- Remove extra delays between enabling things. The sensor requires 8192
clock cycles after the reset is lifted before I²C access, so 1 ms is
enough.
- Make the delay after lifting xshutdown 10 ms. This guarantees that
streaming will only start once the sensor has had enough time to settle
after lifting the reset.
