NiceHCK Octave is an OEM of TTGK TT39039F01-PROMAX[1] and supports DSD64/
DSD128/DSD256/DSD512[2].
It advertises the UAC2 RAW_DATA format on altsetting 4 of its playback
interface, but without the DSD_RAW quirk flag the driver exposes it only as
a SPECIAL format that cannot be used.
Add QUIRK_FLAG_DSD_RAW for the device (USB ID 3302:39c3), so the altsetting
is exposed as DSD_U32_BE, enabling native DSD playback.
