Jiewen Yao 11a6cc5bda MdeModulePkg/PciBus: Add IOMMU support. 
If IOMMU protocol is installed, PciBus need call IOMMU
to set access attribute for the PCI device in Map/Ummap.

Only after the access attribute is set, the PCI device can
access the DMA memory.

Wei Liu 5624a27dde MdeModulePkg: introduce PcdPciDisableBusEnumeration 
Platforms such as Xen already enumerates PCI bridges and devices. Use
this PCD to control EDK2 behavior.

PcdPciDisableBusEnumeration is placed under [PcdsFixedAtBuild,
PcdsPatchableInModule, PcdsDynamic, PcdsDynamicEx], so that it is
possible to alter it during runtime.

The default setting of this PCD is false (allow full PCI enumeration) to
preserve the same behavior before this change.
