Currently mem_type_to_tile() is being used to access the tile's underlying tile.mem.vram. However, this function makes the assumption that a mem_type will only ever map to a single tile. Now that the TTM vram manager contains a pointer to the memory_region, make use of this in xe_bo.c. As such, introduce a helper function res_to_mem_region() to get the ttm_vram_mgr->vram from the BO's resource, and use this to replace usage of mem_type_to_tile(). xe_tile is still needed to choose the migration context, so this part is unchanged. But as this is only renaming usage, function is renamed now to mem_type_to_migrate().

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.
