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.

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.
