Set periodic task to be triggered by HRTIM

For now control task is set by timer 6, but measurement acquisition is triggered by HRTIM. This leads to timing uncertainty and non determinism of the control task because of the DMA interupts.

The second problem is that we need to have determinism not only at the module level, but at the system level, when multiple modules are synched. The control tasks must be synched as it will clearly prevent a lot of control issues related to asynch control of different modules delivering power to the same load.

The envisioned solution is to trigger the execution of the control task on HRTIM timer instead of Timer 6. This will both solve the module level non determisn as well as the system level issue, as the system have synchronization based on HRTIM sync in and sync out.

This was solved in commit #8b83764d.
