[patch] perf_event DRAM RAPL uses wrong units on Broadwell-EP

[Vince Weaver]

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.
