soundwire: cadence: rename sdw_cdns_dai_dma_data as sdw_cdns_dai_runtime
The existing 'struct sdw_cdns_dma_data' has really nothing to do with
DMAs. The information is stored in the dai->dma_data, but this is
really private data that should be stored in a different context.
Beyond the academic elegance discussion, using dma_data is a problem
for new Intel hardware where the dma_data structure is already used
for true DMA handling performed by other parts of the code.
This patch prepares a transition away from the use of dma_data, for
now with a rename-only change.
