* This function takes in a DML pipe (pipe_e2e) and predicts if pipe split is required (both

* determined by DPPClk requirements
*
* This function follows the same policy as DML:
* - Check for ODM combine requirements / policy first
* - MPC combine is only chosen if there is no ODM combine requirements / policy in place, and
*   MPC is required
*
* Return: Number of splits expected (1 for 2:1 split, 3 for 4:1 split, 0 for no splits).
