i915: prevent pre-gen9 from using tile modifiers with AR24

Prior to gen 9, the kernel rejects creating framebuffers with the AR24
format and a tiling modifier, so detect that case and force the modifier
to linear.

This change also adds device IDs for all gens (sourced from mesa's
i965_pci_ids.h and iris_pci_ids.h) so that the chip's gen can be
accurately identified.

TEST=Boot on devices with gen7, gen8, and gen9 Intel GPUs, verify UI comes up
