    xen/arm: pci: Narrow scope of file-local symbols
    
    Make pci_alloc_host_bridge() and pci_add_host_bridge() in
    pci-host-common.c, rcar4_pcie_ops and rcar4_pcie_child_ops in
    pci-host-rcar4.c, and nwl_pcie_ops in pci-host-zynqmp.c static, as
    they are only used within their respective translation units.
    
    Also include pci-host-rcar4.h in pci-host-rcar4.c so that the
    declarations of its externally visible functions are visible at the
    point of definition.
    
    This resolves MISRA C Rule 8.4 violations.
