ALSA: hda - Add a fixup for internal mic on MacBook Pro 8,1
The internal mic on MBP81 gives only the right channel, and the left channel is static. Add a verb to fix the ADC2 channel mode to expand mono right to stereo. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=50781 Signed-off-by: Takashi Iwai <tiwai@suse.de>
