So what's the difference to "fast-charge-safe-current"?

Some of the properties are quite generic and used on multiple
chips, so we may create a power_supply/battery-fuel-gauge.txt
and power_supply/battery-charger.txt with generic bindings.

I'm fine with just adding vendor prefixed properties for all
instances, though.
