Subject: [PATCH v6 0/2] perf pmus: Sort/merge/aggregate PMUs like mrvl_ddr_pmu

The mrvl_ddr_pmu is uncore and has a hexadecimal address
suffix. Current PMU sorting/merging code assumes uncore PMU names
start with uncore_ and have a decimal suffix. Add support for
hexadecimal suffixes and add tests.

v6. Add necessary fix in pmu.c to perf_pmu__match_ignoring_suffix that
    also needs to ignore hex suffixes.
v5. In pmus.h remove needless addition of #include list.h but add
    stddef.h for size_t.
v4. Workaround GCC build error by using unsigned types. Don't consider
    short hex suffixes as suffixes (e.g. cpum_cf) and test this
    behavior.
v3. Rebase and move tests from pmus.c to the existing pmu.c.

  perf tests: Add some pmu core functionality tests
