We will be using extra logs during enabling of the SR-IOV features
or when adding support for new platforms. Define separate config
flag to keep that low level logs disabled if we're not debugging.

Add some basic unit tests for rtp. This is intended to prove the
functionality of the rtp itself, like coalescing entries, rejecting
non-disjoint values, etc.
Contrary to the other tests in xe, this is a unit test to test the
sw-side only, so it can be executed on any machine - it doesn't interact
with the real hardware. Running it produces the following output:
$ ./tools/testing/kunit/kunit.py run --raw_output-kunit \
--kunitconfig drivers/gpu/drm/xe/.kunitconfig xe_rtp

Note that the ERRORs in the kernel log are expected since it's testing
incompatible entries.
v2:
- Use parameterized table for tests (Michał Winiarski)
- Move everything to the xe_rtp_test.ko and only add a few exports to the
right namespace
- Add more tests to cover FIELD_SET, CLR, partially true rules, etc

This seems to be the preferred nomenclature in xe. Currently we are
intermixing vram and lmem, which is confusing.
v2 (Gwan-gyeong Mun & Lucas):
- Rather apply to the entire driver

We currently don't have any tests that explicitly depends on this
config option, so remove that build dependency.

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:
