ALSA: usb-audio: apply quirk for Playstation PDP Riffmaster

This device, just like the Playstation 5's DualSense, has a volume
that's too low, hid-playstation solves this by raising the minimum
volume on the device itself by sending an output report, third party PS5
controllers/accessories do not support this output report format, so we
apply a quirk to raise the minimum volume by 6dB.
