I don't think ./dt-bindings/gpio/gpio.h is the right source of these
defines for everyone - including non-OF systems. I would prefer the
ones in include/linux/gpio/machine.h be the upstream source but then
headers in include/dt-bindings/ cannot include them so my second-best
suggestion is to rename the ones in include/linux/gpio/machine.h and
treewide too. In general values from ./dt-bindings/gpio/gpio.h should
only be used in DTS sources and gpiolib-of code.
