[0/3] driver/tool fix for SPR Dram RAPL Domain

Message

Intel Xeon servers used to use a fixed energy resolution (15.3uj) for
Dram RAPL domain, starting from HasWell-X.

But on SPR, this changes.
The Dram RAPL domain uses 61uj energy resolution, which follows the
standard energy resolution as described in MSR_RAPL_POWER_UNIT.

There are a couple of places that have implemented the energy unit quirk
for SPR Dram RAPL domain, including intel-rapl driver, rapl perf pmu and
the turbostat tool.

This patch series fixes them all, although they belong to different
components.

thanks,
