ICM426xx - Avoid long startup delays when target allows 42605 and 

42688P.

If the target has a 42688P sensor there is a 20*150ms (3 second) delay
caused by the 42605 driver's detect code.

The 42605/42688P sensors are pin-compatible so it makes sense that a
target would specify BOTH sensors to allow flexibility in manufacturing.
