PciConfigIo is a legacy pci bus dispatcher, which manages all pci devices including a pci root bridge. However, it is unnecessary to design a complex hierarchy which redirects every access by PciRoot. Since pci root bridge is also a pci device instance, and only contains easy config space read/write, and PciConfigIo actually acts as a pci bus to dispatch resource based resolving when VMExit, we re-arrange to make the pci hierarchy clean.
