MdeModulePkg/PciBus: Should reserve enough bus number for HPC
When there is no bridge before the HPC (hot plug controller), the issue cannot be seen. But when there are bridges before the HPC, the PciBus will only use the value (= <CurrentBusNumber> + <ReservedBusNumber>) as the sub-ordinary bus number for HPC. The correct sub-ordinary bus number should be: <CurrentBusNumber> + <OccupiedBusNumber>(by earlier bridges) + <ReservedBusNumber>.
