ConfigureL2IPMCs configures the events of both L2s to be the same.
The first L2 is tied to cores 0-3. The second is tied to cores 4-7. Events for a specific L2 must be read from a core tired to the specific L2.
L2 transactions are 64 bytes.

Index	Event	Description
0	Reserved
1	L2MissICFill	The number of IC requests that miss the L2
2	L2MissDCFill	The number of DC requests that miss the L2
3	L2MissPrefetchFill	The number of prefetch requests that miss the L2
4	L2MissAll	The total number of L2 Misses
5	L2Writeback	The number of L2 clean and dirty writebacks
