There are three groups of platforms using i915->irq_mask independently: gen 2-4, VLV/CHV, and gen 5-7. The gen 5-7 usage is primarily limited to display. Move its irq_mask usage to struct intel_display as ilk_de_imr_mask for gen 5-7. ilk_de_imr_mask could be put inside a union with with vlv_imr_mask and de_irq_mask[], but keep them separate to avoid accidental aliasing of the values. With this, we can also drop the irq_mask member from struct xe_device.

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.
