Works for me, as long as I can drop the dependency on display/intel_display_reg_defs.h. Just let me know.

To avoid deps on display/, it would be here, i915_reg_defs.h, or a new file that would mostly just contain this kind of offsets.

I suppose it could just live in intel_gt_regs.h for the moment?

CHV_FUSE_GT (0x182168) is purely about GT fuses, therefore belongs in intel_gt_regs.h, is in the gcfgmmio unit, but is technically in the VLV display base area. Use the 0x182168 MMIO address directly to drop dependency on VLV_DISPLAY_BASE and thus display/intel_display_reg_defs.h in intel_gt_regs.h.
