soc: bcm: Move power-domain drivers to the genpd dir

To simplify with maintenance let's move the bcm power-domain drivers to the
new genpd directory. Going forward, patches are intended to be managed
through a separate git tree, according to MAINTAINERS.

While moving the drivers, we end up with a directory for bcm63xx that only
contains a Kconfig file, which seems a bit silly. Let's therefore also move
the Kconfig options into the Kconfig file a directory above, as it allows
us to drop the directory too.

genpd: Create a new subsystem directory to host genpd providers

There are currently ~60 users of the genpd provider interface, which
implementations are sprinkled across various subsystems. To simplify with
maintenance let's create a new subsystem (drivers/genpd) and start moving
the providers in there.

My intention is also to host a git tree to collect and to get the patches
tested/integrated through the linux-next tree. Ideally this should release
some of the burden on the soc maintainers.

Note that, I will of course require acks/reviews from the current platform
maintainers, hence the MAINTAINERS file needs to be updated accordingly for
each genpd provider that is moved into the new genpd subsystem.

bpf,docs: Create new standardization subdirectory

The BPF standardization effort is actively underway with the IETF. As
described in the BPF Working Group (WG) charter in [0], there are a
number of proposed documents, some informational and some proposed
standards, that will be drafted as part of the standardization effort.

[0]: https://datatracker.ietf.org/wg/bpf/about/

Though the specific documents that will formally be standardized will
exist as Internet Drafts (I-D) and WG documents in the BPF WG
datatracker page, the source of truth from where those documents will be
generated will reside in the kernel documentation tree (originating in
the bpf-next tree).

Because these documents will be used to generate the I-D and WG
documents which will be standardized with the IETF, they are a bit
special as far as kernel-tree documentation goes:

- They will be dual licensed with LGPL-2.1 OR BSD-2-Clause
- IETF I-D and WG documents (the documents which will actually be
standardized) will be auto-generated from these documents.

In order to keep things clearly organized in the BPF documentation tree,
and to make it abundantly clear where standards-related documentation
needs to go, we should move standards-relevant documents into a separate
standardization/ subdirectory.

selftests: cgroup: Add cpuset migrations testcase

Add a separate testfile to verify treating permissions when tasks are
migrated on cgroup v2 hierarchy between cpuset cgroups.

In accordance with v2 design, migration should be allowed based on
delegation boundaries (i.e. cgroup.procs permissions) and does not
depend on the migrated object (i.e. unprivileged process can migrate
another process (even privileged) as long as it remains in the original
dedicated scope).

MAINTAINERS 2: Electric Boogaloo

We just sorted the entries and fields last release, so just out of a
perverse sense of curiosity, I decided to see if we can keep things
ordered for even just one release.

The answer is "No. No we cannot".

I suggest that all kernel developers will need weekly training sessions,
involving a lot of Big Bird and Sesame Street. And at the yearly
maintainer summit, we will all sing the alphabet song together.

I doubt I will keep doing this. At some point "perverse sense of
curiosity" turns into just a cold dark place filled with sadness and
despair.

docs: remove the tips on how to submit patches from MAINTAINERS

Having "how to submit patches" in MAINTAINTERS seems out of place.
We have a whole section of documentation about it, duplication
is harmful and a lot of the text looks really out of date.

Sections 1, 2 and 4 look really, really old and not applicable
to the modern process.

Section 3 is obvious but also we have build bots now.

Section 5 is a bit outdated (diff -u?!). But I like the part
about factoring out shared code, so add that to process docs.

Section 6 is unnecessary?

Section 7 is covered by more appropriate docs.

This initial driver supports a subset of types of counter.
It supports counters that are either fixed or configurable, but requires
that they support the ability to freeze and write value whilst frozen.
