Create a new xe_tile structure to begin separating the concept of "tile" from "GT." A tile is effectively a complete GPU, and a GT is just one part of that. On platforms like MTL, there's only a single full GPU (tile) which has its IP blocks provided by two GTs. In contrast, a "multi-tile" platform like PVC is basically multiple complete GPUs packed behind a single PCI device. For now, just create xe_tile as a simple wrapper around xe_gt. The items in xe_gt that are truly tied to the tile rather than the GT will be moved in future patches. Support for multiple GTs per tile (i.e., the MTL standalone media case) will also be re-introduced in a future patch. v2: - Fix kunit test build - Move hunk from next patch to use local tile variable rather than direct xe->tiles[id] accesses. (Lucas) - Mention compute in kerneldoc.

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.
