Revert "ALSA: hda: Add codec on bus address table lately"
This reverts commitee5f85d929
("ALSA: hda: Add codec on bus address table lately"). The commit caused several regression since I've overlooked that the function doesn't manage only the caddr_tbl but also the codec linked list that is referred indirectly in the other drivers. Revert for now to make everything back to work. Fixes:ee5f85d929
