 * Insert DPP into MPC tree based on specified blending position.

 * [in/out] mpc		- MPC context.
 * [in/out] tree	- MPC tree structure that plane will be added to.
 * [in]	blnd_cfg	- MPCC blending configuration for the new blending layer.
 * [in]	sm_cfg		- MPCC stereo mix configuration for the new blending layer.
 *			  stereo mix must disable for the very bottom layer of the tree config.
 * [in]	insert_above_mpcc - Insert new plane above this MPCC.  If NULL, insert as bottom plane.
