These four commits are perf supporting for nds32.
There are three perfomance counters in nds32, and
each of them can counts different events. You can
use 'perf list' to show the available events that
can be used.

Furthermore, NDS32 SPAv3 is not able to detect it is read or write.
It only know either it is instruction fetch or data access.
Therefore, by removing the wrong flag assignment(actually, the hardware
is not able to show the reason), we can fix this bug.

The patches are about unaligned access handler. We fix some
bugs in unaligned access handler and add some kernel configs
for unaligned access handler. Then we add the kernel unaligned
access handled by software in handler.

If the kernel config 'CONFIG_ALIGNMENT_TRAP' and the file
'/proc/sys/nds32/unaligned_access/enable' are set, the kernel
unaligned access handler does not handle correctly when the
value of immediate field is negative. This commit fixes the
unaligned access handler in kernel.
