[Impact]
On Dell's platform, Warlock/Bullseye Laptops have a mono DMIC, Cyborg and
some Warlock variants uses a stereo DMIC. They are not correctly mapped
to the corresponding configurations so the microphone function are not
working as expected.

[Fix]
Cirrus upstream new FIXUPs to support different microphone configurations
on different Dell laptop variants.

[Test Case]
1. Go to Audio Settings
2. Make sure the microphone is correctly detected and responds to audio input.
3. Issue command "arecord record_file" and check the record_file is consistent 
   with audio input.

[Where problems could occur]
Risk should be Low. The patches come from Cirrus and the configurations
are mapped based on the audio codec's SSIDs for different Dell variants.
