x86/gpu: add CFL to early quirks

CFL was missing from intel_early_ids[]. The PCI ID needs to be there to
allow the memory region to be stolen, otherwise we could have RAM being
arbitrarily overwritten if for example we keep using the UEFI framebuffer,
depending on how BIOS has set up the e820 map.

Fixes: b056f8f3 ("drm/i915/cfl: Add Coffee Lake PCI IDs for S Skus.")
