 Align field names in ID_AA64DFR0_EL1 with architecture")

Hi All,

The builds of arm64 allmodconfig have failed to build next-20220919
with the error:

drivers/perf/arm_spe_pmu.c: In function 'arm_spe_pmsevfr_res0':
drivers/perf/arm_spe_pmu.c:679:14: error: 'ID_AA64DFR0_PMSVER_8_2' undeclared (first use in this function); did you mean 'ID_AA64DFR0_EL1_PMSVer_IMP'?

git bisect pointed to c0357a73fa4a ("arm64/sysreg: Align field names in ID_AA64DFR0_EL1 with architecture").

I will be happy to test any patch or provide any extra log if needed.
