ASoC: msm: Enable PCM capture in compressed driver

In the use case of HDMI input PCM capture, timestamp received from
DSP is required in userspace to propogate it on the playback path.
Timestamp mode propagation is availble through the meta data mode
in compressed driver. Add support for PCM capture in compressed
driver to address the usecase
