regulator: event: Add regulator netlink event support
This commit introduces netlink event support to the regulator subsystem.
Changes:
- Introduce event.c and regnl.h for netlink event handling.
- Implement reg_generate_netlink_event to broadcast regulator events.
- Update Makefile to include the new event.c file.
