3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel J Blueman <daniel@quora.org>
commit 16337e028a6dae9fbdd718c0d42161540a668ff3 upstream.
Correctly enable the digital microphones with the right bits in the right coeffecient registers on Cirrus CS4206/7 codecs. It also prevents misconfiguring ADC1/2.
This fixes the digital mic on the Macbook Pro 10,1/Retina.
