Jani Nikula b9241d0ed9 drm/{i915, xe}/display: duplicate gen2 irq/error init/reset in display irq
Duplicate gen2_irq_reset(), gen2_assert_iir_is_zero(), gen2_irq_init(),
gen2_error_reset(), and gen2_error_init() in intel_display_irq.c.

This allows us to drop the duplicates from xe, and prepares for future
cleanups. Although duplication is undesirable in general, in this case
the local duplicates lead to a cleaner end result.

There's a slight wrinkle in gen2_assert_iir_is_zero(). We need to use
non-device based logging until we pass in struct intel_display in a
separate change.

v2:
- Keep xe compat stuff due to series reorder and rebase
- Keep the WARN as regular WARN
- Rename the functions in the same go

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.
