ASoC: qcom: fixes for Click/Pop Noise

Browse Source 
Merge series from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

to accumlate DC when ports are active but without any data streams.
There are multiple places in the current setup, where this could happen
in both startup as well as shutdown path.
