Subject: x86/gpu: add CFL to early quirks

From: Lucas De Marchi <[email protected]>

commit 33aa69ed8aacd92dea12671e52eb3ca6ac2d7a49 upstream.

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 b056f8f3d6b9 ("drm/i915/cfl: Add Coffee Lake PCI IDs for S Skus.")
