Since commit 5acf49119630 ("drm/msm: import gen_header.py script from Mesa"),
compilation is broken on machines having python versions older than 3.9
due to dependency on argparse.BooleanOptionalAction.
Switch to use simple bool for the validate flag to remove the dependency.

Is it now okay to require Python for the build? Not listed in
Documentation/process/changes.rst.

The change to move gen_header.py to kernel is already part of the v6.10
pull request.
This change only fixes the version dependency.
But, I agree we should update the changes.rst (better late than never).
Dmitry, can you pls suggest which version we want to list there?
I am hoping that after this change there are no further dependencies on
python versions, so anything > EOL should be fine.
I am leaning towards v3.8

I doubt it is ok. Perl scripts have been replaced with shell scripts in
the past to speed up the build process. See commit e0e2fa4b515c
("headers_install.pl: convert to headers_install.sh") as an example.

No idea if we're supposed to allow python as a build dependency. That
being said, I can confirm that this fixes the problem for me since I
ran into it too [1].

I do not like Perl.
IMHO, Python should be OK if Perl is OK.
I agree that the required version should be
documented changes.rst, at least.

FWIW, it looks like the commit this is fixing is now present in
Linus's tree. Is there any plan to land this fix? It would be nifty if
it could somehow make it in time for -rc1 so I don't need to track
down this patch every time I need to build a subsystem tree for the
next several weeks...

Irrespective of whether we want to allow Python as a build dependency or
not, it already is since v6.10-rc1, so in the meantime I'm going to
apply this to drm-misc-fixes to unbreak things.
If we decide that we don't want the extra dependency we need revert the
whole generation infrastructure.
