ASoC: fsl: Remove unused inline function imx_pcm_dma_params_init_data()
The imx_pcm_dma_params_init_data() are no longer used since
commit c31da0b196 ("ASoC: imx-ssi: Remove unused driver"),
and the function is used to initialize some members of
"struct imx_dma_data", it's more readable to assign the value
directly, imx_pcm_dma_params_init_data is useless, so remove it.
