drop 2 patches based on RC review feedback

Dropped patches:

- "ALSA: usb-audio: Remove VALIDATE_RATES quirk for Focusrite devices"
  Queues: 5.15
  Reason: maintainer NAK - missing dependency 24d2d3c5f940 ("ALSA: usb-audio:
    Improve Focusrite sample rate filtering") not present in 5.15; without it,
    all sample rates are advertised on every altsetting instead of the correct
    per-altsetting subset
  Report: https://lore.kernel.org/stable/ad0pqOwdPW1s3t4U@m.b4.vu/

- "ALSA: usb-audio: Update for native DSD support quirks"  [dependency]
  Queues: 5.15
  Reason: Stable-dep-of for the above patch; exists solely to provide context
    changes needed by the dropped patch
