Get a rough battery charge estimate until we've seen a high or low
battery level. After that we can use the coulomb counter to calculate
the battery capacity.

Note that I should probably update this to support ocv-capacity-table
before this makes sense to apply. With ocv-capacity-table we should be
able to estimate battery state as described in the documentation for
Documentation/devicetree/bindings/power/supply/battery.txt.

Maybe we should let userspace do that?

Unless this gets integrated in UPower, My point of view is that
userspace probably wants some uniform approach. Kernel interface
definitely is one uniform interface that would also get picked up by UPower.
