Bug description:
  [SRU Justifications]

  ========== firmware-sof ==========

  [Impact]
  The mic-mute led not working on Dell Tarako laptops with Cirrus Audio Codec.

  [Fix]
  For firmware-sof, it required the updated sof-rpl-cs42l43-l0.tplg to remove the useless 'PGA5.0 5 Master Capture Switch' and 'PGA2.0 2 Master Capture Switch' for Mic Mute LED control

  [Test Case]
  1. install firmware-sof-signed with version >= 2023.12.1-1ubuntu1.4.
  2. press mic-mute hot-key and check if mic-mute LED is toggled correctly and aligned with the Mic-Mute status.

  [Where problems could occur]
  The topology only affects the particular Intel platforms with configuration which connects the cs42l43 codec on link #0 of soundwire. Should be low risk for regression.
