    isa_common: allow multiple device instances
    
    In some devices, there may be multiple isa bridges available from different
    sources. Therefore, we allow multiple lpc devices to be generated so that
    pcie bus won't show "none" anymore.
    For example, in my AMD based Framework Laptop, there are two such
    bridges. One is acpi hinted, another is from pcie.
