ASoC: WCD9304: Enable Digital MIC recording
While selecting TX port1 to perform recording using Digital
MIC1, the TX port1 control register on WCD9304 was not being
programmed to specify the DMIC1 connection for the tx port.
Fix by correcting the register sequence for enabling Digital
MIC 1 on WCD9304 and enable channel corresponding to TX port1
