Now the device model only supports the 0..5 PCI bar for PCI/PCIE devices. This tries to allocate the PCI_MEM32 resource for PCI ROM bar. V1->V2: Use the PCI_ROMBAR as bar index and PCIBAR_ROM bar type when calling the pci_emul_alloc_bar to allocate the guest physical addr for PCI ROM bar. And it will allocate the resource from PCIBAR_MEM32 region. V2->V3: Add more comments that describes the parameter of pci_emul_alloc_bar.
