ALSA: hda - Add CS4208 codec support for MacBook 6,1 and 6,2
MacBook 6,1 and 6,2 have a CS4208 codec instead of CS4206/CS4207 on the former models. Most of functions work fine as is, except for the silent speaker output. After debugging sessions, it turned out that the machine needs to set GPIO 0 for the speaker amp. This patch adds the basic support for CS4208 and the fixup for these MacBooks. Basically the codec works just with the generic parser. For re-using the existing GPIO amp code and init/free callbacks, a few places have been changed so that CS4206/4207-specific codes (errata, etc) won't hit with CS4208.
