    intel: add generic functions to check PCI ID · 4e81d4f9
    Lucas De Marchi authored
    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
