We are abusing struct drm_info_list.data by storing there pointer
to the xe_gt, while it shouldn't be used for any device specific
data. Use recently introduced xe_gt_debugfs_simple_show() that
hides all details how to obtain the xe_gt pointer. This will also
remove the need for making copies of the struct drm_info_list
to get GT specific definitions.

Many of our debugfs files are GT specific and require a pointer to
struct xe_gt to correctly show its content. Our initial approach
to use drm_info_list.data field to pass pointer not only requires
extra steps (like copying template per each GT) but also abuses
the rule that this data field should not be device specific.
Introduce helper function that will use xe_gt pointer stored at
parent directory level and use .data only to pass actual print
function that would expects xe_gt pointer as a parameter.

For non-RCS engines, nearly all of the LRC state is composed of MI
instructions (specifically MI_LOAD_REGISTER_IMM). Providing a dump
interface allows us to verify that the context image layout matches
what's documented in the bspec, and also allows us to check whether LRC
workarounds are being properly captured by the default state we record
at startup.
For now, the non-MI instructions found in the RCS and CCS engines will
dump as "unknown;" parsing of those will be added in a follow-up patch.
v2:
- Add raw instruction header as well as decoded meaning. (Lucas)
- Check that num_dw isn't greater than remaining_dw for instructions
that have a "# dwords" field. (Lucas)
- Clarify comment about skipping over ppHWSP. (Lucas)

The XE_WARN_ON macro maps to WARN_ON which is not justified
in many cases where only a simple debug check is needed.
Replace the use of the XE_WARN_ON macro with the new xe_assert
macros which relies on drm_*. This takes a struct drm_device
argument, which is one of the main changes in this commit. The
other main change is that the condition is reversed, as with
XE_WARN_ON a message is displayed if the condition is true,
whereas with xe_assert it is if the condition is false.

Since memory and address spaces are a tile concept rather than a GT
concept, we need to plumb tile-based handling through lots of
memory-related code.
Note that one remaining shortcoming here that will need to be addressed
before media GT support can be re-enabled is that although the address
space is shared between a tile's GTs, each GT caches the PTEs
independently in their own TLB and thus TLB invalidation should be
handled at the GT level.
v2:
- Fix kunit test build.

The media GT requires a valid gt->kernel_bb_pool during driver probe to
allocate the WA and NOOP batchbuffers used to record default context
images. Dynamically allocate the bb_pools so that the primary and media
GT can use the same pool during driver init.
The media GT still shouldn't be need the USM pool, so only hook up the
kernel_bb_pool for now.

Add debugfs entry to dump the final tables with register save-restore
information.
For the workarounds, this has a format a little bit different than when the
values are applied because we don't want to read the values from the HW
when dumping via debugfs. For whitelist it just re-uses the print
function added for when the whitelist is being built.

Sort includes and split them in blocks:
1) .h corresponding to the .c. Example: xe_bb.c should have a "#include
"xe_bb.h" first.
2) #include <linux/...>
3) #include <drm/...>
4) local includes
5) i915 includes
This is accomplished by running
`clang-format --style=file -i --sort-includes drivers/gpu/drm/xe/*.[ch]`
and ignoring all the changes after the includes. There are also some
manual tweaks to split the blocks.

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).
The new Xe driver leverages a lot from i915.
As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.
This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
