Merge tag 'davinci-boards-delete-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into arm/soc

Delete the two DaVinci board families DM644x and DM646x.

The reason why I'm pushing for this is that I have floated
patches to update the board files to use GPIO descriptors,
iterated and fixed bugs in the patches reported by reviewers
and build robots, and then the patches have not been merged.
See:

v6:
https://lore.kernel.org/linux-arm-kernel/20201103000158.325147-1-linus.walleij@linaro.org/
https://lore.kernel.org/linux-arm-kernel/20210715191141.430307-3-linus.walleij@linaro.org/

v7:
https://lore.kernel.org/linux-arm-kernel/20220507124536.171930-1-linus.walleij@linaro.org/
https://lore.kernel.org/linux-arm-kernel/20220507124536.171930-2-linus.walleij@linaro.org/

I assume this is not getting merged because of lack of interest
in the platform, and such things happen. To save myself and
others from spending work hours on maintaining and modernizing
a platform that is not used, delete the board files.
