So far we've added the devices that need vendor/product string renames or the profile setup into the standard quirk table in quirks-table.h. This table is imported into the primary USB audio device entry, hence it's all exported for the probing so that udev and co can take a look at it. OTOH, for renaming or profile setup, we don't need to expose those explicit entries because the probe itself follows the standard way. That said, we're exposing unnecessarily too many entries. This patch moves such internal quirk entries into the own table, and reduces the exported device table size. Along with the moving items, re-arrange the entries in the proper order.
