perf/x86: Fix Broadwell-EP DRAM RAPL events
It appears as though the Broadwell-EP DRAM units share the special units quirk with Haswell-EP/KNL. Without this patch, you get really high results (a single DRAM using 20W of power). The powercap driver in drivers/powercap/intel_rapl.c already has this change.
