[PATCH] dma-fence: add get_signaled_timestamp to fence ops

latencies. The get_signaled_timestamp ops, if defined by the driver would be used during fence signaling to set the timestamp, before setting the flag DMA_FENCE_FLAG_TIMESTAMP_BIT. If the callback is not defined, ktime_get is used to set the fence timestamp. Signed-off-by: Veera Sundaram Sankaran
