perf arm-spe: Support multiple Arm SPE PMUs
A platform can have more than one Arm SPE PMU. 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_'.
