The driver tracks the time spent by NPU executing jobs and shares it through sysfs `npu_busy_time_us` file. It can be then used by user space applications to monitor device utilization. NPU is considered 'busy' starting with a first job submitted to firmware and ending when there is no more jobs pending/executing.
