The multi-link structure needs to be handled whether the DSP is enabled or not. The host and link DMAs are only relevant when the DSP is enabled. Things get convoluted when there's an ambiguity between the LOSIDV settings in the multi-link register space and the selection of the stream_tag for the link DMA. Clarify with a rename that the static functions used are related to the host and link DMAs only. No functionality change, pure rename.
