Duncan Laurie fa1a7c49f7 battery: Allow BATTERY_LEVEL_NEAR_FULL to be defined by board ...

Allow the board to override the hardcoded 97% value for reporting to
the host (and controlling LED behavior) when the battery is "near full".

When enabling "discharge on ac" with a full battery the battery stops
taking a charge until it reaches ~94% SOC (the actual value is not set
but rather comes from a smart battery status bit) but the user will see
the device as discharging between 97% and 94%.

The host side view can be worked around with a powerd preference.
The LED behavior is all inside the EC, so you end up with the LED showing
discharging when it should not.

If we allow the board to override this to 94% then the LED and host
behavior is consistent.
