power: supply: core: add power_supply_for_each_device()

Introduce power_supply_for_each_device(), which is a wrapper
for class_for_each_device() using the power_supply_class and
going through all devices.

This allows making the power_supply_class itself a local
variable, so that drivers cannot mess with it and simplifies
the code slightly.
