xen/pci: Add a function to reset device for xen
When device on dom0 side has been reset, the vpci on Xen side won't get notification, so that the cached state in vpci is all out of date with the real device state. To solve that problem, add a new function to clear all vpci device state when device is reset on dom0 side. And call that function in pcistub_init_device. Because when using "pci-assignable-add" to assign a passthrough device in Xen, it will reset passthrough device and the vpci state will out of date, and then device will fail to restore bar state.
