Add some pre-assumption and safety check for PCIe ECAM:
1) ACRN only support platforms with PCIe ECAM to access PCIe device CFG space;
2) Must not use ECAM to access PCIe device CFG space before
pci_switch_to_mmio_cfg_ops was called. (In release version, ACRN didn't support
IO port Mechanism. ECAM is the only way to access the PCIe device CFG space).
