we specifically put this into dts as almost each of the SoC versions
has a different register layout. i really want to avoid having to
patch the gpio driver whenever ralink/mtk decides to "change the
registers yet again". I can change it if must be. but i really would
prefer to keep it this way as it will safe me lots of time in future
