Enable battery charging detection for iBasso DX50/DX90.
This changes iBasso DX50/DX90 config from CHARGING_SIMPLE (Simple, hardware
controlled charging (CPU cannot read charger state but may read when power is
plugged-in) to CHARGING_MONITOR (Hardware controlled charging with monitoring
(CPU is able to read HW charging state and when power is plugged-in)).
Not really usefull at the moment, since USB connection (charging) is not (yet)
gracefully handled for iBasso devices.
