[HACK] ASoC: soc-pcm: relax requirement on direction check

The patches added a requirement that the cpu and codec dais support the direction set by the dailink. One some Intel platform, we "cheat" when the echo reference is generated. The dailink is marked as supporting capture even though the amplifier cannot generate the echo reference; the echo reference is actually generated in the firmware and the DAI not used for capture proper.
