This patch just unconditionally sets the flag in all drivers which will
break any system which relies on the existing behaviour that we ignore
GPIO 0.  We can definitely set this flag in any DT only system if we get
the GPIO from DT but otherwise doing this defeats the point of having
the flag in the first place.
