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.
