ASoC: msm: Enable initial/trailing silence removal 



For gapless audio playback, the DSP HW decoder needs to
remove the initial and trailing samples from the decoder
output according to meta data present in the stream. This
change is to enable the silence removal by sending the
meta data down to DSP.
