========== 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.
