perf/marvell: Fix !CONFIG_OF build for CN10K DDR PMU driver

When compiling the Marvell CN10K DDR PMU driver with CONFIG_OF=n, the
build fails:

  | drivers/perf/marvell_cn10k_ddr_pmu.c:723:35: error: 'cn10k_ddr_pmu_of_match' undeclared here (not in a function); did you mean 'cn10k_ddr_pmu_driver'?

Use `of_match_ptr()` to avoid referencing the non-existent match table
in this configuration.
