Max Zhen 489a8539ca accel/amdxdna: Expose NPU device busy time via DRM fdinfo
Expose NPU device engine busy time through DRM fdinfo to enable
standardized userspace monitoring and profiling.

Add support for reporting per-engine busy time in nanoseconds via fdinfo
using the "drm-engine-npu" key. The value reflects the accumulated NPU
device execution time for a given process, allowing userspace tools to
observe NPU device utilization without driver-specific ioctls.
