hv: vpci: hv: vpci: refine pci device assignment logic

Browse Source 
Now Host Bridge and PCI Bridge could only be added to SOS's acrn_vm_pci_dev_config.
So For UOS, we always emualte Host Bridge and PCI Bridge for it and assign PCI device
to it; for SOS, if it's the highest severity VM, we will assign Host Bridge and PCI
Bridge to it directly, otherwise, we will emulate them same as UOS.
