Mikko Perttunen 303267d828 gpu: host1x: Implement job tracking using DMA fences ...

In anticipation of removal of the intr API, implement job tracking
using DMA fences instead. The main two things about this are
making cdma_update schedule the work since fence completion can
now be called from interrupt context, and some complication in
ensuring the callback is not running when we free the fence.
