Subject: perf/marvell: Fix !CONFIG_OF build for CN10K DDR PMU driver
Git-commit: 6676a42f1e4f1b8ec166b723a3801b7113c25a0e
Patch-mainline: v5.18-rc1
References: jsc#PED-1765

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.
