2.1.1.11.2 BoosterPack Site 2 Power Isolation

JP8 is included to isolate 3.3V and 5V from the BoosterPack site 2 headers. This can be required if two BoosterPacks are simultaneously connected to the LaunchPad and both provide power to the LaunchPad. If this is the case, then power can be isolated by removing the shunts on JP8 and there is no contention between the two BoosterPacks.
