power: supply: core: add wakeup source inhibit by power_supply_config

To inhibit wakeup users currently have to use dedicated functions to
register the power supply: {,devm_}power_supply_register_no_ws().
This is inconsistent to other runtime settings which can be configured
through struct power_supply_config.
It's also not obvious what _no_ws() is meant to mean.

Extend power_supply_config to also be able to inhibit the wakeup source.
