    xen/public: arch-arm: Restrict the visibility of struct vcpu_guest_core_regs
    
    Currently, the structure vcpu_guest_core_regs is part of the public API.
    This implies that any change in the structure should be backward
    compatible.
    
    However, the structure is only needed by the tools and Xen. It is also
    not expected to be ever used outside of that context. So we could save us
    some headache by only declaring the structure for Xen and tools.
    
    [Stefano: improve comment code style]
