This series introduces KUnit[1] tests for TTM (Translation Table Manager)
subsystem, a memory manager used by graphics drivers to create and manage
memory buffers across different memory domains, such as system memory
or VRAM.
Unit tests implemented here cover two data structures:
- ttm_device -
Add the initial version of unit tests for ttm_device struct, together
with helper functions.

This patch is a preparation for replacing enum i915_cache_level with PAT
index. Caching policy for buffer objects is set through the PAT index in
PTE, the old i915_cache_level is not sufficient to represent all caching
modes supported by the hardware.

Don't populate the const array on the stack, instead make it static.

The functions drm_framebuffer_plane{width,height} and
fb_plane_{width,height} do exactly the same job of its
equivalents drm_format_info_plane_{width,height} from drm_fourcc.
The only reason to have these functions on drm_framebuffer
would be if they would added a abstraction layer to call it just

Bring up the SM6125 DPU now that all preliminary series (such as INTF
TE) have been merged (for me to test the hardware properly), and most
other conflicting work (barring ongoing catalog *improvements*) has made
its way in as well or is still being discussed.
