hisl_0079: Connections to root input/output ports

ID: Title	hisl_0079: Connections to root input/output ports
Description	To improve traceability, adhere to the internal connection constraints on the root-level Inport and Outport blocks of the current model.
Note	When internal connections to the root-level port blocks of a model are invalid, the software silently inserts hidden blocks to satisfy the constraints wherever possible. The hidden blocks can result in generated code without traceable requirements.
Rationale	Improve robustness of design.
Model Advisor Checks	Check for invalid root input and output port connections (Simulink Check)
