power: supply: core: fix charge_behaviour formatting

Browse source

This property is documented to have a special format which exposes all
available behaviours and the currently active one at the same time. For
this special format some helpers are provided.

When the charge_behaviour property was added in
1b0b6cc803 ("power: supply: add charge_behaviour attributes"), it did
not update the default logic in in power_supply_sysfs.c to use the
format helpers. Thus by default only the currently active behaviour
is printed. This fixes the default logic to follow the documented
format.

There is currently only one in-tree drivers exposing charge behaviours -
thinkpad_acpi, which is not affected by the change, as it directly uses
the helpers and does not use the power_supply_sysfs.c logic.
