Draft: d/patches: Add FP5 speaker patch

To extract the firmware:

{ name = "aw882xx_acf.bin", rename = "aw88261_acf.bin" },

need to be added to

https://gitlab.com/mobian1/droid-juicer/-/blob/master/configs/fairphone,fp5.toml?ref_type=heads#L4

For unknown reasons,

mobian@mobian:~$ sudo modprobe snd-soc-aw88261

is needed to probe the amp.
