xen/pvh: Setup gsi for passthrough device

Browse Source 
In PVH dom0, the gsis don't get registered, but the gsi of
a passthrough device must be configured for it to be able to be
mapped into a domU.

When assigning a device to passthrough, proactively setup the gsi
of the device during that process.
