[Sound-open-firmware] [PATCH] topology: add implementations for single direction pcm

[Keyon Jie]

Currently it support only dual direction pcm with PCM_DUPLEX_ADD,
definitely we need add single direction(playback or capture only)
pcm in many cases.

Here add implementation of PCM_PLAYBACK_ADD add PCM_CAPTURE_ADD,
for playback and capture respectively.
