Paulo Zanoni 68eb49b140 drm/i915: refactor the IRQ init/reset macros
The whole point of having macros here is for the token pasting
necessary to automatically have IMR, IIR and IER selected. We don't
really need or want all the inlining that happens as a consequence.
The good thing about the current code is that it works regardless of
the relative offsets between these registers (they change after gen4,
with the usual VLV/CHV exceptions).

One thing which we can do is to split the logic of what we do with
imr/ier/iir to functions separate from the macros that pick them.
That's what we do in this commit. This allows us to get rid of the
gen8 duplicates and also all the inlining:

v2:
 - Make checkpatch happy with a temporary which_ (Checkpatch).
 - Reorder the arguments for the INIT macros (Ville).
 - Correctly explain when the register offsets change in the commit
   message (Ville).
 - Use more line breaks in the macro calls to make the arguments look
   a little more organized/readable.
 - Update the bloat-o-meter output (minor change only).

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 Restructured Text 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.
