Andrey Semin 40ee8e3b9d tools/power turbostat: correct DRAM RAPL units on recent Xeon processors
While not yet documented in the Software Developer's Manual,
the data-sheet for modern Xeon states that DRAM RAPL ENERGY units
are fixed at 15.3 uJ, rather than being discovered via MSR.

Before this patch, DRAM energy on these products is over-stated by turbostat
because the RAPL units are 4x larger.
