alpha: implement HW performance events on the EV67 and later CPUs
This implements hardware performance events for the EV67 and later CPUs within the Linux performance events subsystem. Only using the performance monitoring unit in HP/Compaq's so called "Aggregrate mode" is supported. The code has been implemented in a manner that makes extension to other older Alpha CPUs relatively straightforward should some mug wish to indulge themselves.
