[RFC PATCH] MAINTAINERS: Add note on patches to MAINTAINERS itself

[Paul Barker <paul@pbarker.dev>]

Since there is no entry in the maintainers list for the MAINTAINERS file
itself, we should add a short note on how to handle patches to this
file.

I'm in the process of updating device tree files as part of $JOB and
would like to add relevant entries to the MAINTAINERS file. I've
searched through the maintainer list, read what I can find in the docs
and ran scripts/get_maintainer.pl but I can't see a clear statement of
where to send patches which modify MAINTAINERS. Looking at a couple of
examples of previous patches which modified MAINTAINERS and looking up
the relevant emails on lore.kernel.org I've made my best guess on how
these changes should be handled. This patch adds that best guess as a
note to the MAINTAINERS list so it's easy for folks to find in the
future.

This is an RFC as others probably know the correct way to handle patches
to the MAINTAINERS file. Even if this "best guess" is wrong I hope it
highlights that such a note would be useful. I've treated this patch as
a docs patch, please let me know if it should be sent to different
maintainers/lists.
