Sampling grouping and channel packing are two separate concepts in SoundWire. In addition, the bandwidth allocation allocates a vertical slice for each stream, which makes the use of the PER_CHANNEL packing mode irrelevant. Let's use the proper definition for block packing mode (PER_PORT). This change has no functional impact though since the net result is the same configuration of the DPN_BlockCtrl3 register, when implemented.
