pciconf.txt

I recently acquired a Lenovo V15 G4 laptop (an AMD laptop) and although headphone output works fine, speaker output does not.

After some digging the speaker was labeled as "disconnected" and thus never had audio routed to it.

Adding this to /boot/device.hints fixed it:

```
hint.hdaa.1.nid20.config="as=1 seq=0 device=speakers"
hint.hdaa.1.nid33.config="as=1 seq=15 device=Headphones"
```

but I figure it'd be nice to have the mux work properly out of the box.

I'm not the first person with this problem either! See https://forums.freebsd.org/threads/lenovo-ideapad-3i-realtek-alc257-without-sound-and-mic.93980/ who ended up with the same answer.
