I'm not sure how these pci compatibles are usually handled. Do they have to
be added to the dt-bindings Documentation as well or is it fine to just have them
here since they're not really used to match anything?

Otherwise this looks good to me,

I suppose they have to be added (at least for dtb validation) but 
"pci14e4,4433" is already in net/wireless/brcm,bcm4329-fmac.yaml.  Added 
via e2e37224e8b3 ("dt-bindings: net: bcm4329-fmac: Add Apple properties 
& chips").
