 I would suggest just removing the #if NGPIO conditionals.  Compile that code 
 You will also need to separate the "search for children" code, which looks like 
 it consists only of a call to config_found_ia(..," gpiobus", ...), into a 
 separate function pxagpio_rescan() and add the rescan function to the 
 CFATTACH_DECL_NEW (you'll need to update that to use CFATTACH_DECL3_NEW).
