Applied with Takashi's reviewed-by to pci/iommu for v6.12, thanks!

I changed the hex to lower-case to match nearby code and dropped the
#defines for PCI_DEVICE_ID_GLENFLY_ARISE10C0_AUDIO and
PCI_DEVICE_ID_GLENFLY_ARISE1020_AUDIO since they aren't used.
If those values are used in more places than the quirk, we can add
them and use the #defines in all the places.
