[PATCH] power: supply: core: simplify charge_behaviour formatting

[Thomas Weißschuh]

The function power_supply_show_charge_behaviour() is not needed and can
be removed completely.
Removing the function also saves a spurious read of the property from
the driver on each call.

The convulted logic was a leftover from an earlier patch revision.
Some restructuring made this cleanup possible.
