msm: camera2: Add monotonic timestamp for SOF

Browse source 
In Camera3, SOF (start of frame) event indicates the time imager
starts to expose. Its timestamp is used for frameworks to do AV
sync for video recording, which needs to use kernel monotonic
clock source. Hence add a new field in the event structure to pass
this along.
