Thread-topic: [Xen-devel][PATCH 1/3] VT-d: support Intel IGD passthrough
Some registers of Intel IGD are mapped in host bridge, so it needs to 
passthrough these registers of physical host bridge to guest because emulated 
host bridge in guest doesn't have these mappings. 

Some VBIOSs and drivers ssume the IGD BDF (bus:device:function) is always 
00:02.0, so this patch reserves 00:02.0 for assigned IGD in guest.
