Add a way to hint to the fence signaler of an upcoming deadline, such as
vblank, which the fence waiter would prefer not to miss. This is to aid
the fence signaler in making power management decisions, like boosting
frequency as the
The general approach seems to make sense now I think.
One minor thing which I'm missing is adding support for this to the
dma_fence_array and dma_fence_chain containers.

As the finished fence is the one that is exposed to userspace, and
therefore the one that other operations, like atomic update, would
block on, we need to propagate the deadline from from the finished
fence to the actual hw fence.

dma_fence_array looks simple enough, just propagate the deadline to
all children.
I guess dma_fence_chain is similar (ie. fence is signalled when all
children are signalled), the difference being simply that children are
added dynamically?
