[PATCH 09/31] ASoC: intel/sdw_utils: move soundwire machine driver helper functions

[Vijendar Mukunda <Vijendar.Mukunda@xxxxxxx>]

Move below Intel SoundWire machine driver helper functions to
soc_sdw_utils.c file so that it can be used by other platform machine
driver.
- asoc_sdw_is_unique_device()
- asoc_sdw_get_codec_name()
