    LinuxKPI: add struct dmi_header and unsupported dmi_walk()
    
    Add a structure definition as well as a dummy dmi_walk for now
    which returns an error as not supported.  Our current dmi implementation
    is special but does not give access to all details but rather only
    information from kenv which does not suffice all use cases.
