power: supply: core: remove {,devm_}power_supply_register_no_ws()

The same functionality is available through
power_supply_config::no_wakeup_source, which is more idiomatic.
All users of the old API have been converted.

Also remove the argument "ws" from __power_supply_register(),
as it is now always "true".
