Ok i will switch that to a simple y without a CONFIG item to it, and
start that inheritance chain at SIEMENS_SIMATIC_IPC.
That in fact also makes sure the interface does not change and "make
olddefconfig" does not turn the Siemens stuff back off because the
newly introduced guard is blocking/hiding what used to be turned on.
