ALSA: usb-audio: Add native DSD support for Luxman DA-06
Add native DSD support quirk for Luxman DA-06 DAC, by adding the PID/VID 1852:5065. Rename "is_marantz_denon_dac()" function to "is_itf_usb_dsd_2alts_dac()" to cover broader device family sharing the same USB audio implementation(*). For the same reason, rename "is_teac_dsd_dac()" function to "is_itf_usb_dsd_3alts_dac()". (*) These devices have the same USB controller "ITF-USB DSD", supplied by INTERFACE Co., Ltd. "ITF-USB DSD" USB controller has two patterns, Pattern 1. (2 altsets version) - Altset 0: for control - Altset 1: for stream (S32) - Altset 2: for stream (S32, DSD_U32) Pattern 2. (3 altsets version) - Altset 0: for control - Altset 1: for stream (S16) - Altset 2: for stream (S32) - Altset 3: for stream (S32, DSD_U32) "is_itf_usb_dsd_2alts_dac()" returns true, if the DAC has "Pattern 1" USB controller, and "is_itf_usb_dsd_3alts_dac()" returns true, if "Pattern2".
