[PATCH 1/2] perf: imx9_ddr_perf: resolve resource map conflict

[Xu Yang]

Usually, the ddr pmu node will be a subnode of DDR controller, then using
devm_platform_ioremap_resource will report conflict with DDR controller
resource. So update the driver to use devm_ioremap to avoid such
resource check.
