perf/x86: Fix broken PEBS-LL support on SNB-EP/IVB-EP
This patch fixes broken support of PEBS-LL on SNB-EP/IVB-EP. For some reason, the LDLAT extra reg definition for snb_ep showed up as duplicate in the snb table. This patch moves the definition of LDLAT back into the snb_ep table. Thanks to Don Zickus for tracking this one down.
