Apparently not, as the old legacy number still works, and it doesn't work
without.

As far as I understand it, on Armadillo this is used more for platform
configuration than for device configuration, as it affects multiple devices
(the comment says DBGMD/LCDC0/FSIA MUX).

I guess I could use a "gpio-hog" subnode in DT instead, but then we're already
implementing the conversion to DT ;-)

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
