    sim/ppc: mark device_error function as ATTRIBUTE_NORETURN
    
    The device_error function always ends up calling the error function,
    which is itself marked as ATTRIBUTE_NORETURN, so it makes sense that
    device_error should also be marked ATTRIBUTE_NORETURN.
    
    Doing this resolves a few warnings from hw_ide.c about possibly
    uninitialized variables - the variables are only uninitialized after
    passing through a call to device_error, which obviously means the
    variables are never really used uninitialized, the simulation will
    terminate with the device_error call.
