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.
