[PATCH 5.19 090/717] powercap: intel_rapl: Use standard Energy Unit for SPR Dram RAPL domain

[Greg Kroah-Hartman]

From: Zhang Rui <rui.zhang@xxxxxxxxx>

commit 4c081324df5608b73428662ca54d5221ea03a6bd 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.
