Jernej Skrabec ef54f1dc24 drm: sun4i: de2/de3: add generic blender register reference function
The DE2 and DE3 engines have a blender register range within the
mixer engine register map, whereas the DE33 separates this out into
a separate display group.

Prepare for this by adding a function to look the blender reference up,
with a subsequent patch to add a conditional based on the DE type.

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.
