Partially restore the handling of the GPU load history. Accumulate the
busy_time and and total_time measured in active state during the polling
period. This results in slightly smoother picture of the GPU frequencies
(measured on the a530/msm8996, using kmscube in different resolutions).

Add a new flag to let userspace provide a deadline as a hint for syncobj

The initial purpose is for igt tests, but this would also be useful for
compositors that wait until close to vblank deadline to make decisions
about which frame to show.
The igt tests can be found at:

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.

This series adds a deadline hint to fences, so realtime deadlines
such as vblank can be communicated to the fence signaller for power/
