ASoC: Rename s3c24xx_pcm prefix to s3c_dma

Browse Source 
The s3c24xx_pcm prefix for the soc_platform is inappropriate when
some Samsung SoCs have PCM controllers which will eventually have
drivers and hence namespace ambiguities.

To resolve naming ambiguities in future the following have been
renamed in order
1) s3c24xx_pcm_dma_params -> s3c_dma_params
2) s3c24xx_pcm_preallocate_dma_buffer -> s3c_preallocate_dma_buffer
3) s3c24xx_pcm_dmamask -> s3c_dma_mask
4) s3c24xx_pcm_XXX -> s3c_dma_XXX
