Prashant Malani 6157db5d51 gpu: nvgpu: gk20a: Update perfmon init ...

Make the perfmon sampling configurable, by adding an 'enabled' flag.
This is set according to the CONFIG initially. Modify the perfmon event
handler to not touch clock rates. Add a counter to count the number of
perfmon events.

Also add debugfs entries for the above.
