Yes, however a kconfig case where you can set the minimum value of an
integer would make the whole extra-gpio configuration much cleaner and
avoid having toadd further configuration symbols when someone wants an
extra 256 or whatever GPIOS.

Having a dynamic GPIO range would also be nice, someone should look at
adding it to the GPIO code.
