for gpio_t and cpu_t



Hello,

Following is a tentative fix for #bug 28901. I have modified it for one file 
iox128a1.h. Would like to carry out similar changes to remaining xmega headers 
if the fix looks fine. I had to introduce a suffix '_r' so as not to collide 
with similar macros defined. Let me know your comments.
