    PCI: Use a weak symbol for the empty version of 
pcibios_add_platform_entries()
    
    I'm not sure if this is going to fly, weak symbols work on the compilers I'm
    using, but whether they work for all of the affected architectures I can't 
say.
    I've cc'ed as many arch maintainers/lists as I could find.
    
    But assuming they do, we can use a weak empty definition of
    pcibios_add_platform_entries() to avoid having an empty definition on every
    arch.
