BatteryDefender: Explicitly set wireless path to reduce errors logs

Browse source 
For gs101 devices, we must detect whether a wireless charger exists at
runtime, otherwise we'd need to create separate Health.cpp for each
product in order to instantiate the wireless path correctly.

Test: Ensure battery defender triggers via wireless connection.
   Ensure there are no warnings for devices that do not have a wireless
   charger
