ASoC: wcd9335: Infinite loop when routing DMIC for handset ANC

When routing DMIC input to ANC block for handset ANC usecase,
codec driver enters an infinite loop attempting to determine
the stream sample rate. Additionally since the noise DMIC is
configured prior to the rest of the usecase, we cannot deterine
the stream sample rate to configure the ANC block for half-rate.
Therefore revert that logic and let ANC block be configured
according to the device tree.
