drivers/perf: imx_ddr: Add DDR performance counter support to perf
Add DDR performance monitor support for iMX8QXP. The PMU consists of 3 programmable event counters and a single dedicated cycle counter. Example usage: $ perf stat -a -e \ imx8_ddr0/read-cycles/,imx8_ddr0/write-cycles/,imx8_ddr0/precharge/ ls - or - $ perf stat -a -e \ imx8_ddr0/cycles/,imx8_ddr0/read-access/,imx8_ddr0/write-access/ ls Other events are supported, and advertised via perf list.
