I am not following. we just agreed a couple of weeks ago to record ALL
Intel/HDaudio PCI IDs in the same pci_ids.h include file.

ArrowLake-S is the first addition to first file after the work done by
Cezary/Amadeusz. Yes it's required to be added since it'll be used in
other parts later on. But even if there was ONE use of this PCI ID, why
would we not add it for consistency to the global pci_ids.h file?
Takashi's hda_intel.c file would look really bad if we have a mix of
single-use PCIs and shared ones...

Oh and heads-up that I have a change for LunarLake that will require
Mark to pull the branch from Takashi :-)
