Takashi Iwai 6ab982e8cf ALSA: hda - Fix pin configurations for MacBook Air 4,2 
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.

* 6. At high temperature (TA > +85°C), the digital supply current (IVD)
* may be excessive (up to an additional 200 μA), which is most easily
* observed while the part is being held in reset (RESET# active low).
*
* Root Cause: At initial powerup of the device, the logic that drives
* the clock and write enable to the S/PDIF SRC RAMs is not properly
* initialized.
* Certain random patterns will cause a steady leakage current in those
* RAM cells. The issue will resolve once the SRCs are used (turned on).
*
* Workaround: The following verb sequence briefly turns on the S/PDIF SRC
* blocks, which will alleviate the issue.

* Description:
* 1. Performance degredation is present in the ADC.
* 2. Speaker output is not completely muted upon HP detect.
* 3. Noise is present when clipping occurs on the amplified
* speaker outputs.
*
* Workaround:
* The following verb sequence written to the registers during
* initialization will correct the issues listed above.
