accel/amdxdna: Support sensors for column utilization

The AMD PMF driver provides realtime column utilization (npu_busy)
metrics for the NPU. Extend the DRM_IOCTL_AMDXDNA_GET_INFO sensor
query to expose these metrics to userspace.

Add AMDXDNA_SENSOR_TYPE_COLUMN_UTILIZATION to the sensor type enum
and update aie2_get_sensors() to return both the total power and up
to 8 column utilization sensors if the user buffer permits.
