ALSA: hda - Fix pin configurations for MacBook Air 4,2

Browse Source 
commit 6ab982e8cf upstream.

MacBook Air 4,2 requires the whole default pin configuration table to
be overridden by the driver, as usual, as Apple's machines don't set
up properly after boot.  Otherwise mic won't work, and other ill
effect may happen.
