Single PCI bus driver instance will manager all PCI Root Bridges in one EFI based firmware,
since all PCI Root Bridges' resources need to be managed together.
Supported() function will try to get PCI Root Bridge IO Protocol.
Start() function will get PCI Host Bridge Resource Allocation Protocol to manage all
PCI Root Bridges. So it means platform needs install PCI Root Bridge IO protocol for each
PCI Root Bus and install PCI Host Bridge Resource Allocation Protocol.
