HV: repace vpci_vdev_array with pci_ptdev config

Browse Source 
Use acrn_vm_pci_ptdev_config struct for PCI PT devices configuration
in acrn_vm_config, the only needed configure item is PT devices's
vBDF and pBDF info. When init PT devices, the BDF info will be stored
in pci_vdevs[] of acrn_vm.

With this patch, the previous vpci_vdev_array struct is not needed.
