perf: arm_cspmu: nvidia: monitor all ports by default

2024-12-09T15:07:49Z

Some NVIDIA PMUs like the NVLINK-C2C, CNVLINK, and PCIE PMU provide port filtering. If the port filter is set to zero, the counter of these PMUs will not capture any event. To avoid meaningless experiment, the driver sets the port filter value to a default non-zero value.
