[ Upstream commit b2d433ae637626d44c9d4a75dd3330cf68fed9de ]

Intel Xeon servers used to use a fixed energy resolution (15.3uj) for
Dram RAPL domain. But on SPR, Dram RAPL domain follows the standard
energy resolution as described in MSR_RAPL_POWER_UNIT.

Remove the SPR rapl_dram_energy_units quirk.
