Karthik Anantha Ram a130199cd3 msm: camera: sync: Add support for dma fences 
Add support to create, release, signal and import
a dma fence. When a sync object is imported for a dma fence
signal the dma fence when signaling the sync object with
appropriate status. This is achieved by implementing
generic fence scheme. The change also adds support
for batched fences.
