Documentation refers to outdated EQ files

[JohnAZoidberg]

https://thesofproject.github.io/latest/developer_guides/tuning/sof-ctl.html

refers to:

• eq_iir_flat.txt
• eq_iir_bandpass.txt
• eq_iir_bassboost.txt
• eq_iir_loudness.txt
• eq_fir_flat.txt
• eq_fir_mid.txt
• eq_fir_loudness.txt

All don't exist anymore. Are there other files I can try? If yes, what commands do I have to run?
