For example, a system with multiple clusters may have each cluster enabled with its own Arm SPE instance. In such case, the PMU devices will be named 'arm_spe_0', 'arm_spe_1', and so on. Currently, the tool only supports 'arm_spe_0'. This commit extends support to multiple Arm SPE PMUs by detecting the substring 'arm_spe_'.
