sync: Support timestamp passing
Timestamps read in an interrupt handler and when fence state
is being updated can differ by variable amount. That
add unnecessary jitter to original interrupt times.
This patch adds support for passing timestamp from the device
driver thereby allowing more accurate timestamps.
