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".

Queued for 4.17 now. I put some line breaks appropriately in the changelog text above, as some of them are too long for git-log.
thanks,
