wifi: ath12k: Add timestamp to dp stats display
In MLO configurations the device_dp_stats debugfs file is read
separately for each ath12k device. Without a timestamp it is impossible
to know whether two snapshots were taken at the same moment, making
counter comparisons across devices unreliable.
Prepend a ktime-based millisecond timestamp to the output header so the
reader can confirm when the snapshot was taken.
