This will allow platforms to reuse kernel IDs instead of manually
keeping them in sync. In most of the cases we only need to extend
IS_9XX(). Current platforms that fit this requirement can be ported
over to use this macro. Right now it's a nop since it doesn't have any
PCI ID added.
The i915_pciids.h header is in sync with kernel tree on
drm-tip 2018y-08m-20d-21h-41m-11s.
v2: - move to a separate .c so we can have the array in a single
compilation unit
- use a single array for all gens
- add real functions to get or check gen by pciid
- define our own pci device struct rather than inherit the one
kernel uses: we can throw away most of the fields
v3: - add comment to keep ids sorted by gen
- remove misleading comment about all gens
