Analog/digital MEMS extension connector CN6 and CN8

The CN6 and CN8 connectors allows to connect STEVAL-MKI0xxV1 MEMS demonstration
boards (gyroscope, accelerometer) that are compatible with 24 DIL socket. The MEMS
extension must be fitted in both connectors CN6 and CD8 in the same time. The MEMS
extension when plugged uses only the right half of the CN8 connector terminals. The left
half is free even if the MEMS extension is plugged.
