The GPIO controller is at the same address in all of the
currently known chips so create a node for it in the base
dtsi.

Some extra properties are needed to actually use it so
disable it by default.

Eventually this should go through the ARM SoC tree, but
it is fine to send with the rest of the patches, I will simply
just apply 1-3.
