platform/x86: intel: Add notifiers support
In some cases a driver using services of vsec_tpmi driver requires some
processing before vsec_tpmi exits. For example a children using debugfs
can't use debugfs as this will be deleted by the vsec_tpmi driver.
This is the case when unbind using PCI driver interface. In this case
the remove callback of vsec_tpmi driver is called first, then remove
callback of its children.
Add support of blocking chain notifiers support. Notify on successful probe
and before clean up in the remove callback.
