CHARGE_CONTROL_LIMIT is a wrong property to report charge current limit,
because `CHARGE_*` attributes represents capacity, not current. The
correct attribute to report and set charge current limit is
CONSTANT_CHARGE_CURRENT.

Rename CHARGE_CONTROL_LIMIT to CONSTANT_CHARGE_CURRENT.

Indeed CHARGE_CONTROL_LIMIT looks like a mistake.

Sebastian, my concern now is whether this change would be considered a
userspace ABI breakage.

Other than that, LGTM.
