ASoC: WCD9304: remove dependency between DMIC's and Decimators.
ASoC: WCD9304: remove dependency between DMIC's and Decimators.

The source of input signal(ADC or DMIC) needs to configured correctly
in CDC_TXn_MUX_CTL registers for correct operation of Decimators.
Currently for DMIC's, this configuration is done in DMIC DAPM widget
power up/down call back creating dependency between DMIC number and
Decimator number (with current code, DMIC1 can send signal to only
DEC1, DMIC2 can send signal to only DEC2). Remove this dependency by
setting type of input signal when Decimator MUX input is set.
