Dmytro Laktyushkin 6566cae7ae drm/amd/display: fix odm scaling
There are two issues with scaling calculations, odm recout
calculation and matching viewport to actual recout.

This change fixes both issues. Odm recout calculation via
special casing and viewport matching issue by reworking
the viewport calcualtion to use scaling ratios and recout
to derrive the required offset and size.

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.
