Don't do this, we spent a lot of time to collect drivers in
in drivers/gpio this is counter to our ambitions to have the
drivers under drivers/* and only arch code under arch/*.

Create a new file named loongson2-64bit.c or so and just
ignore that this one exist is an option, as is actually
integrating this driver properly.
