Adds perf events support for L2 cache PMU.

The L2 cache PMU driver is named 'l2cache_0' and can be used
with perf events to profile L2 events such as cache hits

Since this is a bool, you shouldn't need module.h in your driver or

You're right - I'll clean up the include list and sort it alphabetically
while I'm at it.
