Merge branch 'for-thermal-genetlink-family-bind-unbind-callbacks'

Stanislaw Gruszka says:

====================
thermal/netlink/intel_hfi: Enable HFI feature only when required

The patchset introduces a new genetlink family bind/unbind callbacks
and thermal/netlink notifications, which allow drivers to send netlink
multicast events based on the presence of actual user-space consumers.
This functionality optimizes resource usage by allowing disabling
of features when not needed.
