Subject: [PATCH] wireplumber: Update equalizer configuration for DT770

Parametric Equalizer configuration was generated by running the below
command.

```bash
python -m autoeq --input-file="measurements/Kuulokenurkka/data/over-ear/Beyerdynamic DT 770 Pro (80 Ohm).csv" --output-dir="dt770-results" --target="targets/Diffuse field 5128.csv" --parametric-eq --convolution-eq --fs=44100,48000
```
