ALSA: hda - Move a part of hda_codec stuff into hdac_device
Now some codes and functionalities of hda_codec struct are moved to hdac_device struct. A few basic attributes like the codec address, vendor ID number, FG numbers, etc are moved to hdac_device, and they are accessed like codec->core.addr. The basic verb exec functions are moved, too.
