PCI hotplug: create symlink to hotplug driver module
Create symbolic link to hotplug driver module in the PCI slot directory (/sys/bus/pci/slots/<SLOT#>). In the past, we need to load hotplug drivers one by one to identify the hotplug driver that handles the slot, and it was very inconvenient especially for trouble shooting. With this change, we can easily identify the hotplug driver.
