powercap: intel_rapl: Use standard Energy Unit for SPR Dram RAPL domain 

ANBZ: #9623

commit 7db60fd46e0c8492f72551010f50fc6b39909fbb stable

commit 4c081324df upstream.

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 dram_domain_energy_unit quirk.
