[PATCH RFC v2 0/7] drm/msm: generate register header files

[Dmitry Baryshkov]

Currently display-related register headers are generated from XML files
shipped withing Mesa source tree. This is not fully optimal: it requires
multi-stage process of the changes first being landed to Mesa and only
then synced to the kernel tree.

Move original XML files to the kernel tree and generate header files
when required.

NOTE: the gen_header.py script is based on the non-merged Mesa MR [1].
Once that MR lands, I will update the script and commit messages and
send the next iteration.

Changes in v2:
- Removed the _shipped files, always generating the headers (Masahiro
  Yamada)
- Replaced headergen2 with gen_headers.py
- Simplify Makefile rules, making all Adreno objects depend on Adreno
  headers and all displau objects depend on all display headers
- Also handle Adreno registers
- Link to v1: https://lore.kernel.org/r/20240226-fd-xml-shipped-v1-0-86bb6c3346d2@linaro.org
