8a088542c8 powerpc/perf: Use PM_INST_DISP for generic instructions sample
Since PM_INST_CMPL may not provide right counts in all
sampling scenarios in power9 DD1, instead use PM_INST_DISP.
Patch also update generic instruction sampling with the same.

27593d72c4 powerpc/perf: Use MSR to report privilege level on P9 DD1
SIER and SIAR are not updated correctly for some samples, so force the
use of MSR and regs->nip instead for misc_flag updates. This is done by
adding a new ppmu flag and updating the use_siar logic in
perf_read_regs() to use it, and dropping the PPMU_HAS_SIER flag.
