ASoC: soc-dai.h: remove symmetric_xxx from snd_soc_dai

ALSA SoC has some duplicate parameter.
snd_soc_dai::symmetric_xxx are one of them.

commit f0fba2a ("ASoC: multi-component - ASoC Multi-Component
Support") moved "symmetric_xxx" flags from snd_soc_dai to
snd_soc_dai_driver. No one is using snd_soc_dai::symmetric_xxx now.
Let's remove it
