If we use DCC modifiers this can increase the number of planes from the initial 1 plane with metadata, so that we get a valid modifier from getfb2. Since the code didn't update the format_info getfb2 would only ever return 1 plane with a modifier for which userspace expects > 1. This moves the format lookup to amdgpu_display.c so we do not have issues when DC is not compiled.

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.
