Commit Message

Vijendar Mukunda Aug. 1, 2024, 11:18 a.m. UTC 
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().
