tool: make management of PCI D-states by guest optional
D3hot state in some PCI devices causes the failure of domain
creation/destruction.
The default is "pci_power_mgmt=3D0" which disables the guest OS from
managing D-states because it would be better to avoid the trouble than
advantage of low power consumption.
