Power Supply Fixes for 5.16 cycle

Browse Source 
Three fixes for the 5.16 cycle:
 
 1. Avoid going beyond last capacity in the power-supply core
 2. Replace 1E6L with NSEC_PER_MSEC to avoid floating point calculation
    in LLVM resulting in a build failure
 3. Fix ADC measurements in bq25890 charger driver
