thermal: netlink: Add genetlink bind/unbind notifications
Introduce a new feature to the thermal netlink framework, enabling the
registration of sub drivers to receive events via a notifier mechanism.
Specifically, implement genetlink family bind and unbind callbacks to send
BIND and UNBIND events.
The primary purpose of this enhancement is to facilitate the tracking of
user-space consumers by the Intel HFI driver. By leveraging these
notifications, the driver can determine when consumers are present
or absent.
