docs: ! @brief Setter for current HNONSEC value used for memory transactions.
          
          Not all MEM-APs support control of HNONSEC. In particular, only the AHB5-AP used for
          v8-M Cortex-M systems does. The AXI-AP for Cortex-A systems also allows this control.
      
          @param value 0 is secure, 1 is non-secure.
