Jani Nikula cc7e1a9b59 drm/i915/irq: duplicate HAS_FBC() for irq error mask usage
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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
