pcie_root_port: Add hotplug disabling option
Make hot-plug/hot-unplug on PCIe Root Ports optional to allow libvirt
manage it and restrict unplug for the whole machine. This is going to
prevent user-initiated unplug in guests (Windows mostly).
Hotplug is enabled by default.
Usage:
-device pcie-root-port,hotplug=off,...
If you want to disable hot-unplug on some downstream ports of one
switch, disable hot-unplug on PCIe Root Port connected to the upstream
port as well as on the selected downstream ports.
