Revert "ASoC: snd_soc_of_parse_daifmt(): Handle SND_SOC_DAIFMT_SPDIF"

This reverts commit 7e44b46.

On top of that it also removes the SND_SOC_DAIFMT_SPDIF defines. The
spdif interface was not really being handled in any codec driver.

In our DT's the SPDIF interface should be handled through the
adv7511_audio code. This registers a platform device that is handled by
the hdmi-codec sound codec that in turn handles SPDIF by setting a
different macro named HDMI_SPDIF. That is what is used in the
adv7511 code.
