  2. ipc4: add host_dma_config array 

    Add host_dma_config array to be able to keep multiple
DMA tlv pointers. This change is needed to enable SNDW
FW aggregation using HD-A DMA on LNL

  3. ipc4: add helper function to parse dma config 

    Add helper function to parse muiltiple DMA config tlv structures
added to copier Init Instance IPC in case of SNDW FW aggregation.

To be able to find correct config we need to iterate over the
sequence of DMA tlv with the same tlv type. Thus, we need to check
if device_address value (which contains PDI) is equal to device_id
parameter (passed with alh_id value).

  4. copier: dai: use HD-A dai to configure soundwire on LNL 

    Since LNL soundwire uses HD-A DMA to transfer data. Add LNL specific
configuration to select HD-A DMA in case of SoundWire audio interface.
Refactor copier dai code for sndw/alh node id type.

Add support for sndw link aggregation mode for LNL platform based on
DMA config being sent during Copier Init Instance IPC.
