    xen/arm: Fix mapping for PCI bridge mmio region
    
    Current code skip the mapping for PCI bridge MMIO region to dom0 when
    pci_passthrough_enabled flag is set. Mapping should be skip when
    has_vpci(d) is enabled for the domain, as we need to skip the mapping
    only when VPCI handler are registered for ECAM.
