The error irq handling needs to mask page table errors on gen 2/3 with
FBC. See commit e7e12f6ec8 ("drm/i915: Mask page table errors on
gen2/3 with FBC") for details.
We want to avoid using display feature checks in i915 core code. Since
FBC can't be fused off on gen 2/3, just list the platforms that support
FBC. Add a macro purely for making the code self-documenting.
With this, we can drop the intel_display_core.h include, and make struct
intel_display opaque inside i915_irq.c.
