ASoC: uniphier: drop selecting non-existing SND_SOC_UNIPHIER_AIO_DMA

Commit f37fe2f9987b ("ASoC: uniphier: add support for UniPhier AIO common
driver") adds configs SND_SOC_UNIPHIER_{LD11,PXS2}, which select the
non-existing config SND_SOC_UNIPHIER_AIO_DMA.

Hence, ./scripts/checkkconfigsymbols.py warns:

  SND_SOC_UNIPHIER_AIO_DMA
  Referencing files: sound/soc/uniphier/Kconfig

Probably, there is actually no further config intended to be selected
here. So, just drop selecting the non-existing config.
