ypr0: Enable battery voltage read-out, charging monitoring and charger detection.

Browse source 
Voltage can be read using as3543 adc (i.e. ascodec api, on this target implemented
via ioctl()). TODO: Look into possibly controlling charging more by re-using
powermgmt-ascodec.c. However, charging seems to be controlled by the kernel,
so may not be needed.

Charger state can be read using /dev/minivet. It allows to differentiate between
wall charger and usb charging, but that's not implemented (is it even worthwhile?)
