fix #4367 make USB power detection work correctly on seeed trackers (#4376)

Browse Source 
for wio tracker 1110 and 1000-E and possibly other nrf52 boards.
The problem was that nrf52 power stuff wasn't generating regular
powerstatus notifications (because that code was guarded by a batteryLevel
check which was null for those boards).  So I've cleaned up the battery status stuff
a bit and we now have fewer special cases.
Tested on a 1000-E, tracker 1110 and a rak4631 board.
