Jani Nikula c989cb4c64 drm/i915/irq: split ILK display irq handling
Split out display irq handling on ilk. Since the master IRQ enable is in
DEIIR, we'll need to do this in two parts. First, add
ilk_display_irq_master_disable() to disable master and south interrupts,
and second, add (repurposed) ilk_display_irq_handler() to finish display
irq handling.

It's not the prettiest thing you ever saw, but improves separation of
display irq handling. And removes HAS_PCH_NOP() and DISPLAY_VER() checks
from core irq code.

v2:
- Separate ilk_display_irq_master_enable() (Ville)
- Use _fw mmio accessors (Ville)

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.
