ALSA: usb-audio: Add linear volume quirk for Hotone Audio Pulze Mini

Browse Source 
Hotone Audio Pulze Mini is a modeling amplifier with UAC interface. Its
Playback and Capture mixers use linear volume with val = 0/100/1.

Add a quirk table entry matching VID/PID=0x84ef/0x0082 and applying
linear volume quirk flags, so that it can work properly.

Quirky device sample:

  usb 7-1: New USB device found, idVendor=84ef, idProduct=0082, bcdDevice= 1.03
  usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 7-1: Product: Pulze Mini
  usb 7-1: Manufacturer: Hotone Audio
  usb 7-1: SerialNumber: 20240807
