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.
