perf/x86: Enable DRAM RAPL support on Intel Haswell
It turns out all Haswell processors (including the Desktop variant) support RAPL DRAM readings in addition to package, pp0, and pp1. I've confirmed RAPL DRAM readings on my model 60 Haswell desktop. See the 4th-gen-core-family-desktop-vol-2-datasheet.pdf available from the Intel website for confirmation.
