Philipp Zabel de2564c70f gpu: ipu-v3: image-convert: fix image downsize coefficients and tiling calculation 
This patch effectively reverts commit 912bbf7e9c ("gpu: ipu-v3:
image-convert: Fix image downsize coefficients") and replaces it with a
different solution based on the preceding patches.

The previous fix tried to solve the problem of intermediate tile size
between IC downsizing and main processing sections not being limited to
1024 pixels by downsizing the input image to a smaller intermediate size
in the downsizing box filter. This causes unnecessary blurring,
especially for scaling factors close to 1.

Now that the seam position calculation makes sure that the 1024 pixel
intermediate tile size limit is not exceeded, calculate the number of
tiles from the maximum of intermediate size and output size and avoid
unnecessary downsizing.

README 

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.
