This patch adds backtracing capability to oprofile profiling in kernel
and user mode on AVR32. This is done by going through the frames on the
stack and adding oprofile traces for all return addresses. The code
being profiled has to be compiled with frame pointers to make this work.

Move the only thing that was actually implemented and used in
asm/intc.h, intc_get_pending(), into asm/irq.h and delete asm/intc.h

This adds the necessary architecture code to run oprofile on AVR32
using the performance counters documented by the AVR32 Architecture
Manual.
