ASoC: wcd934x: Enable VI path on WCD9340
Speaker protection algorithm needs V(voltage) and I(current) readings from speaker. Enable VI path on the codec to provide readings to the speaker protection algorithm. Change-Id: I741e7f3076a7db595297ad7a1ee551c46d5c8213 Signed-off-by: Sudheer Papothi <spapothi@codeaurora.org>
