Nicholas Kazlauskas c02288724b drm/amd/display: Fix wrong x_pos and y_pos for cursor offload
[Why]
The hubp401_cursor_set_position function programs a different value
than it stores for use with cursor offload.

This can cause a desync when switching between cursor programming paths.

[How]
We do the translation to destination space currently twice: once in the
HWSS layer, and then again in the HUBP layer since we never store the
translated result.

HUBP expects to program the pos->x and pos->y directly for other ASIC,
so follow that pattern here as well.

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.
