ASoC: SOF: ipc4-pcm: Delay reporting is only supported for playback direction

ASoC: SOF: ipc4-pcm: Delay reporting is only supported for playback direction

The firmware does not provide any information for capture streams via the
shared pipeline registers.

To avoid reporting invalid delay value for capture streams to user space
we need to disable it.
