No battery reading on Heltec Wireless Paper 1.2 companion

[witwilinski]

The companion node flashed with 1.11.0 always shows 0% battery and 2.52V voltage, as if it was reading the value from a wrong pin.

Board: Heltec Wireless Paper 1.2.
Meshcore shows the board as Heltec v3

Heltec Wireless Paper 1.2 have some hardware differences from v3. Voltage divider has two 100k resistors. I'm made version for this board at ph1nt@57acfd1
