perf: arm_cspmu: nvidia: monitor all ports by default
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.
