FS#9496 - Deemphasis for WM8731 disabled

The patch turns off deemphasis enabled in WM8731 driver which resulted in pronounced low-pass filtering especially in the 2-10kHz frequency range.
Turning deemphasis off still does not result in a flat frequency response in H10(*), but it seems it have to be like this because H10’s OF produces exactly the same frequency response.
(*) High frequencies, starting at 4kHz, are slightly boosted. Maximum boost is for 18.4kHz and has a value of 4dB.
