The problem is not from your module. Those symbols should have been exported by the kernel. To export request_irq/free_irq, go to arch/nios2nommu/kernel/irq.c, add an include file 

#include <linux/module.h>

then add at the end of the file: 

EXPORT_SYMBOL(request_irq);
EXPORT_SYMBOL(free_irq);

You can do similar change to io.c in the same directory to remove the "warning" about outsw.
