IntelSiliconPkg/header: update PlatformVtdPolicy
Add flexible exception list format: 1) Support Device scope based reporting: Such as, Seg:0/StartBus:0/(Dev:1C|Func:0)/(Dev:0|Func:0) 2) Support PCI VendorId/DeviceId based reporting Such as, VID:8086|DID:9D2F|Rev:21|SVID:8086|SDID:7270 Cc: Star Zeng <star.zeng@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jiewen Yao <jiewen.yao@intel.com> Reviewed-by: Star Zeng <star.zeng@intel.com>
