[ALSA] AD1888 mixer controls for DC mode
This patch adds two mixer controls. The V_REFOUT enable is a documented register that couples the microphone input lines to the V_REFOUT DC source. The High Pass Filter enable in the AC97_AD_TEST2 (0x5c) is an undocumented register provided by Miller Puckette via Analog Devices that enables the AD codec to apply a high pass filter to the input.
