Yes, the point was that I think that it is not good to provide charge_now because
the only use for that is doing things like measure-suspend which require precise data.
If there is no charge_now, then things like measure-suspend can say "go away with
that battery driver".
Userspace can still display some battery state graphics using the "capacity"
sysfs file.
I have seen other drivers not providing charge_now, so we are not doing something
