ASoC: Intel: sof_sdw: add a space before cfg-amp in components

UCM parse amp with Regex " cfg-amp:([0-9]+)". The "ASoC: Intel: sof_sdw:
remove FOUR_SPEAKER quirks" patch removed "cfg-spk:%d " from components
which removed the necessary space as well and cause UCM can't parse the
amp number properly.
