The PCIe devices supported by the PTT trace can be removed/rescanned by hotplug or through sysfs. Add support for dynamically updating the available filter list by registering a PCI bus notifier block. Then user can always get latest information about available tracing filters and driver can block the invalid filters of which related devices no longer exist in the system.
