ASoC: es8328: Add DAPM routes from MIC inputs to Mic Bias

Browse Source 
The ES8328 codec has differential/single-ended microphone inputs
(LINPUT1/RINPUT1, LINPUT2/RINPUT2) that require connection to the
internal Mic Bias generator for proper operation. Currently, these
routes are missing, which can cause microphone recording to fail.

Add the missing DAPM routes to link the input pins to the Mic Bias
supply, ensuring the microphone bias voltage is correctly applied.
