ALSA: hda - Fix pin configurations for MacBook Air 4,2
commit 6ab982e8cf8e5760da407ccdc4abc815bea23179 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.
