[ALSA] ac97 - fix various issues with AD1986/AD1986A support
Previously, ac97_codec.c was coded to support AD1986 and AD1986A CODECs using code written for the AD1985 CODEC. This allowed the LINE_OUT and HEADPHONE jacks to function properly, however register differences between the CODECs prevented line and microphone inputs from functioning. Specifically, this patch fixes issues with the following mixer controls: 'V_REFOUT', 'Spread Front to Surround and Center/LFE', 'Exchange Front/Surround', 'Surround Jack Mode', and 'Channel Mode'. This patch removes the undocumented AD1888 control 'High Pass Filter Enable' and adds the new control 'Exchange Mic/Line In'.
