POWER9: Improve PMU capabilites

[bugproxy]

Hi Canonical,

In order to enable Ubuntu to read the PMU properly on a POWER9 system, the following commits are required:

    a2391b35f1 powerpc/perf: use is_kernel_addr macro in perf_get_misc_flags()
    78a16d9fc1 powerpc/perf: Avoid FAB_*_MATCH checks for power9
    8d911904f3 powerpc/perf: Add restrictions to PMC5 in power9 DD1
    356d8ce3d0 powerpc/perf: Use Instruction Counter value
    8a088542c8 powerpc/perf: Use PM_INST_DISP for generic instructions sample
    a114aca57a powerpc/perf: Add alternative event table and function for power9
    ac19670eb1 powerpc/perf: Add PM_INST_DISP event to Power9 event list
    efe881afdd powerpc/perf: Factor out event_alternative function

We need to have these patches in the kernel if we want to use perf, for example.
