[PATCH v2 01/15] gpio: Disable functions not used with of-platdata

These functions use devicetree and cannot wprl with of-platdata, which has
no runtime devicetree.

If they are used, the current linker error is confusing, since it talks
about missing functions in the bowels of driver model.

Avoid compiling these functions at all with of-platdata, so that a
straightforward link error points to the problem.
