The goal of this patch is to make it possible for the ideapad-laptop
driver to move from its custom conservation_mode sysfs attribute to the
standardised charge_types sysfs attribute with a power_supply extension.
Along with other laptop models which support an end charge threshold
which limits it to a fixed value such as some Toshiba and LG models.

User space, in this case UPower would then be detect 'Long Life' as
charge_types option and set it.

This patch should also allow the "dell-laptop" driver to move over to
the extensions API.
