But they define it if we don't:
#ifndef PORT_AR7
# define PORT_AR7               18
#endif

I don't mind either way. But likely we should reserve the field if we go 
and remove it (setserial has a number->string mapping in busybox). Hm, 
then reserving it or keep it? Perhaps keep it is better... So ack the 
NACK :).
