Bug description:
  [SRU Justifications]

  ========== linux ==========

  [Impact]

  Dell GhostRider comes with Realtek RT722 codec + RT1320 amplifier on
  Intel ARL platform. It needs the latest driver from Realtek on kernel
  6.12 to have all audio function working correctly

  [Fix]
  Backport the patchset from Realtek for RT722 and RT1320 on 6.12.

  
  ========== firmware-sof ==========
  [Fix]
  sof-arl-rt722-l0_rt1320-l2.tplg and sof-arl.ri are required and on the 2.11.2 upstream. 

  ========== alsa-ucm-conf ==========
  [Fix]
  Need following patches for the RT722+RT1320 support.
  d/p/0001-ucm2-soundwire-add-rt722-SDCA-device.patch
  d/p/0001-sof-soundwire-fix-missing-MultiCodec1-initialization.patch
  d/p/0001-ucm2-sof-soundwire-add-RT1320-amplifier.patch
  d/p/0001-rt722-add-mic-led-support.patch

  [Test Case]
  1. Boot up the Dell GhostRider laptops.
  2. Make sure firmware-sof, alsa-ucm-conf and kernel version support RT722+RT1320. 
  3. check with the `aplay -l` commands to see if any valid audio output devices.
  4. Make sure the audio play/record function is working.

  [Where problems could occur]
  It add support the RT722+RT1320 configuration on Intel ARL platform. Also need new firmware-sof and alsa-ucm-conf to support. No regression expected at the current stage.
