ASoC: intel/sdw_utils: refactor init_dai_link() and init_simple_dai_link()
To make it generic, refactor existing implementation for init_dai_link() and init_simple_dai_link() as mentioned below. - Move init_dai_link() and init_simple_dai_link() to common place holder - Rename the functions with "asoc_sdw" as prefix. - Pass the platform specific 'platform_component' structure and its size as arguments for init_simple_dai_link() function and allocate one more extra dlc for platform component. - Pass the 'platform_component' and 'num_platforms' as arguments for init_dai_link().
