[Xen-changelog] [xen staging] x86/ucode: Move interface from processor.h to microcode.h

    x86/ucode: Move interface from processor.h to microcode.h
    
    This reduces the complexity of processor.h, particularly the need to include
    public/xen.h.  Substitute processor.h includes for microcode.h in some
    sources, and add microcode.h includes in others.
    
    Only 4 of the function declarations are actually called externally.  Move 
the
    vendor init declarations to private.h
    
    No functional change.
