This fixes the following error as seen post commit daecf46ee0e5 ("ASoC: soc-core: use snd_soc_dai_link_component for platform") on Apalis TK1 after initial probe deferral:
tegra-snd-sgtl5000 sound: ASoC: Both platform name/of_node are set for sgtl5000 tegra-snd-sgtl5000 sound: ASoC: failed to init link sgtl5000 tegra-snd-sgtl5000 sound: snd_soc_register_card failed (-22) tegra-snd-sgtl5000: probe of sound failed with error -22

Changes in v1: - Split from the Tegra series as suggested by Mark. - Fix issue in soc-core rather than working around it in tegra_sgtl5000.
