I think this needs a bit more, i.e. replacing the rest with respective PCI IDs.

All three will be defined with SST prefix, which makes sense to me.

ACPI here is a bit misleading, but correct. The ACPI specification assumes that
respective part of the ID space covers 100% of PCI ID space.

I have briefly checked the code and it seems that ID is used externally only
for PCI case, so we may simply use the lower 16 bits of the ACPI _HID for the
context.

Do I understand correctly that I should just do:
#define PCI_DEVICE_ID_INTEL_SST_BYT	0x0F28
#define PCI_DEVICE_ID_INTEL_SST_CHV	0x22A8
and use those IDs instead?
