ASoC: Intel: Skylake: Don't use dma I2S config structure in kernel

I2S blob config structure can change between DSP copier module versions.
We are not modifying these structures anyway and NHLT blobs specify them
properly, so use the blob directly to send the dma_control ipc instead
of using the predefined I2S blob config structure.
