[ALSA] AD1888 suspend/resume fix
This patch adds a write to an undocumented register, 0x60 Extended Codec Register Page in the AD1888 codec. It is neccessary in order to make suspend/resume work with the AD1888. Signed-off-by: Jaya Kumar <jayakumar.alsa@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
