We got all the raw event codes covered for P7 with the help of power7-events-list.h
enumeration.

/*
 * Power7 event codes.
 */
#define EVENT(_name, _code) \
	PME_##_name = _code,

enum {
#include "power7-events-list.h"
};
#undef EVENT

Just wondering if its a good idea to name change these selected macros to be consumed
by GENERIC_EVENT_ATTR() right here for this purpose or we need to get the comprehensive
list of raw events for P8 first. Just an idea.
