Now move the all remaining codec drivers from sound/pci/hda to sound/hda/codecs subdirectory. Some drivers are put under the further vendor subdirectory, and the vendor helper code (*_helper.c) are put under helpers subdirectory. Also the sub-codec drivers are moved under a different subdirectory, sound/hda/codecs/sub-codecs, for distinguishing from the main HD-audio codec drivers. The prefix patch_ and hda_ as well as the suffix _helper are dropped from file names as they are mostly superfluous. No functional changes but just file path shuffling.
