ASoC: rsnd: Refactor DMA address tables with named structs

Browse source

Replace the raw multi-dimensional array used for DMA address lookup in
rsnd_gen2_dma_addr() with properly named structs: rsnd_dma_addr (in/out
pair), rsnd_dma_addr_dir (capture/playback arrays), and
rsnd_dma_addr_map (src/ssi/ssiu module sets).

While at it, extract the common lookup logic (is_ssi / use_src / use_cmd
evaluation and table indexing) into a shared rsnd_dma_addr_lookup()
function.

No functional change. This is a preparatory refactor for upcoming RZ/G3E
support which will add its own DMA address map using the same struct and
lookup function.
