Although all current Xe2 platforms support FlatCCS, we probably shouldn't assume that will be universally true forever. In the past we've had platforms like PVC that didn't support compression, and the same could show up again at some point in the future. Future-proof the migration code by adding an explicit check for FlatCCS support to the condition that decides whether to use a compressed PAT index for migration. While we're at it, we can drop the IS_DGFX check since it's redundant with the src_is_vram check (only dGPUs have VRAM).

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.
