[2/3] device: Setup regdom when powering up to maintain consistency

Commit Message

Jussi Laakkonen Dec. 22, 2023, 3:46 p.m. UTC

If the regdom has been set for the technology or for all the
technologies as a global setting apply it when powering up a device that
supports changing regdom. Otherwise the changes made to regdom may not
have been propagated to the device if the change has been made when the
device was powered off, for instance.
