Both the original forward declaration and the new definition are within
the !GPIOLIB case of the #defines, it's just a minimal patch moving the
undefined forward declaration to a defintion.  I didn't want to worry
about reading the individual users to figure out if they had separate
defintions separately to the work to get them all moved over to gpiolib.
