    Adjust function definitions in xen's control.c to avoid clang 15 warnings
    
    With clang 15, the following -Werror warnings are produced:
    
        sys/dev/xen/control/control.c:188:15: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        xctrl_poweroff()
                      ^
                       void
        sys/dev/xen/control/control.c:194:13: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        xctrl_reboot()
                    ^
                     void
        sys/dev/xen/control/control.c:207:14: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        xctrl_suspend()
                     ^
                      void
        sys/dev/xen/control/control.c:344:12: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        xctrl_crash()
                   ^
                    void
    
    This is because xctrl_poweroff(), xctrl_reboot(), xctrl_suspend(), and
    xctrl_crash() are declared with (void) argument lists, but defined with
    empty argument lists. Make the definitions match the declarations.
    
    MFC after:      3 days
    
    (cherry picked from commit a6c803048fd8d4209fb1d52cd3c455a6752109b7)
