fix bug: if PTM-CAP device, like TSN in multi-hostbridge could cause acrn-dm crash. original PTM PCI code has not handled multi-hostbridge case, and just handled hostbridge (00:00.0) case. this patch calls PCI access API to handle PTM-CAP device/bridge (root port) structure, to avoid scan PCI hierarchical.
