Add an identifier sysfs file for the yitian710 SoC DDR and arm CMN to allow userspace to identify the specific implementation of the device, so that the perf tool can match the corresponding uncore events and metrics through the identifier. Then added several general CMN700 metrics and yitian710 soc DDR metrics. $perf list: ... ali_drw: hif_rmw [A Read-Modify-Write Op at HIF interface. 64B.
