ALSA: usb-audio: Add DSD support for iBasso DC04U 



Vendor ID 0x0661 is assigned to Hamamatsu Photonics K.K.,
but is used by iBasso for iBasso DC04U (0x0661:0x0883),
which supports native DSD playback.

This patch adds QUIRK_FLAG_DSD_RAW for iBasso DC04U, enabling
native DSD playback (DSD_U32_BE). The change has been verified
on Arch Linux using mpd and pw-cat.
