R1 Neo - Added OCV_ARRAY from measured discharge curve testing + update ADC multiplier (#8716)

Browse Source 
* Added OCV_ARRAY from measured discharge curve testing and update ADC multiplier

The ADC resistor divider ratio is 0.6 -> multiplier should be 1/0.6 ~=1.667

We data logged a full discharge curve at constant 100mA draw over 15hours to get a realistic voltage curve for battery SoC measurements.

* Remove power.h in favor of variant.h
