ASoC: SOF: ipc4-pcm: Delay reporting is only supported for playback direction
commit 98db16f314b3a0d6e5acd94708ea69751436467f upstream.
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.
