drm/i915: add GT number to intel_device_info
Up to Coffeelake we could deduce this GT number from the device ID.
This doesn't seem to be the case anymore. This change reorders pciids
per GT and adds a gt field to intel_device_info. We set this field on
the following platforms :
- SNB/IVB/HSW/BDW/SKL/KBL/CFL/CNL
Before & After :
$ modinfo drivers/gpu/drm/i915/i915.ko | grep ^alias | wc -l
209
v2: Add SNB & IVB (Chris)
v3: Fix compilation error in early-quirks (Lionel)
v4: Fix inconsistency between FEATURE/PLATFORM macros (Ville)
