charge_state_v2: Basic dual-battery charging algorithm
First version of the algorithm, some TODOs are left in the code
but this, generally, works reasonably well.
When charging, we allocate input current in this general order:
- Base system (fixed, low, number)
- Lid system (based on PSYS)
- Lid battery (estimating how much current the battery actually
requires)
- Base battery (similar estimation)
- Provide everything else to lid
When discharging, we generally:
- First discharge the base battery
- Then discharge the lid battery
BRANCH=none
BUG=b:71881017
TEST=Flash lux and wand, EC-EC communication works, adapter power
is split in a sensible way, and discharging works fine.
