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.
