[libdrm,0/4] intel: rework how we add PCI IDs

Message

Adding PCI IDs to different projects is a boring manual task that
motivated me to create this series. The idea is to centralize the IDs in
the kernel header and let other projects copy it.

Initially my plan was to convert all gens, back to gen2, but that proved
slightly difficult since there are some corner cases to cover and I
didn't want to block the important part, i.e.:  for recent gens, there's
no risk of missing a PCI ID.

It does increase the size a little bit, but doesn't explode. Size diff
below showing ~3k:

-  66237           1384      24   67645   1083d build/intel/intel@@drm_intel@sha/intel_decode.c.o
+  39362            176      40   39578    9a9a build/intel/intel@@drm_intel@sha/intel_bufmgr_gem.c.o
+  68935           1384      24   70343   112c7 build/intel/intel@@drm_intel@sha/intel_decode.c.o

Let me know what you think.

  intel: add IS_GENX() generic macro
  intel: make gen11 use generic gen macro
  intel: make gen10 use generic gen macro
  intel: make gen9 use generic gen macro
