As forwarding interrupts to the non-realtime domain is not a common
use-case of realtime device drivers, I decided to drop the propagation
support at RTDM level. So if you are including this mechanism in your
demo, please mark this pattern as something RTDM drivers should normally
NOT do (and explain what's reason for it here).
